See Lück (1981), ''passim''. It is also evident from the numbering of the reigning counts with the name John.

Like his father, John was never admitted to the [[Order of the Golden Fleece]].<ref name="jansen30" /> John can best be characterised as a wealthy nobleman who faithfully fought in the campaigns for which he was called up; he was not known for spectacular deeds or revolutionary ideas. The campaigns he took part in are therefore more typical of the politics of the Dukes of Burgundy than of his own preferences and interests.<ref name="jansen31" /> Philip ‘the Good’, who since 1430 had been Duke of [[Duchy of Brabant|Brabant]] and since 1433 Count of [[County of Holland|Holland]], the countries in which John’s father’s possessions lay, appointed John already in 1435 or 1436<ref group="note">Van Ditzhuyzen (2004), p.&nbsp;151, Dek (1970), p.&nbsp;69, Blok (1911), p.&nbsp;1218 and Vorsterman van Oyen (1882), p.&nbsp;93 mention the year 1436. Jansen (1979), p.&nbsp;30 and Schutte (1979), p.&nbsp;41 mention the year 1435.</ref> –&nbsp;so before the death of his father&nbsp;– as [[Landdrost|drost]] of Brabant. As drost, he was the highest judicial officer in the duchy who dealt with the cases that did not ressorted to a specific [[court]]. It was not a very politically sensitive office, although he could be assisted by [[Archery|archers]] on foot and horseback and received an annual payment of 600&nbsp;[[Guilder|Philippusguilders]].<ref name="jansen30" /> John held this office until his death.<ref name="ditzhuyzen151" /><ref name="jansen30" /> In 1447 or 1448 John was also appointed drost ([[castellan]]) of the [[Land van Heusden en Altena|Land van Heusden]].<ref group="note">Van Ditzhuyzen (2004), p.&nbsp;152 and Dek (1970), p.&nbsp;69 mention the year 1448. Schutte (1979), p.&nbsp;41 and Vorsterman van Oyen (1882), p.&nbsp;93 mention the year 1447.</ref> Because of Philip the Good’s interest in the [[Middle East]], where his grandfather had suffered a grievous defeat at [[Nikopol, Bulgaria|Nicopolis]] in 1396 that was still unreconciled, and the ever-increasing threat to [[Constantinople]] from the [[Ottoman Empire]], John undertook a journey to the island of [[Rhodes]] on Philip’s orders from May 1441 to February 1442, to see how the infidels could best be combated, but this led to nothing.<ref name="jansen31" /> In the lands of Philip the Good there was still a lot of unrest, like in the County of Holland, where in the 1440’s the struggle between the [[Hook and Cod wars|Hooks and Cods]] had flared up again. In 1445, Philip was obliged to personally put things in order and John was one of the commanders of the [[army]]. John is said to have advised to have the [[city council]]s consist of 50% [[Hook Alliance Treaty|Hooks]] and 50% [[Cod Alliance Treaty|Cods]]. This was not a bad idea, but later [[historian]]s exaggerate when they say that this ended all unrest.<ref name="jansen31" /> More dangerous for Philip was the [[rebellion]] of the [[County of Flanders|Flemish]] [[city]] of [[Ghent]], which wanted to maintain its [[autonomy]] undiminished, and opposed the centralising policy of the Dukes of Burgundy. In 1452 John was part of the army that had to force the rebellious city to obedience. Also the aspirations for autonomy of the city of [[Liège]] clashed with the system of government of the Dukes of Burgundy. Formally, Liège was not even part of the Burgundian territory, but in 1456 a nephew of Philip, [[Louis de Bourbon, Bishop of Liège|Louis of Bourbon]], was forcibly appointed [[Prince-Bishop]] of [[Prince-Bishopric of Liège|Liège]]. In the same year Philip’s illegitimate son [[David of Burgundy]] was appointed [[Bishop]] of [[Prince-Bishopric of Utrecht|Utrecht]].<ref name="jansen31" /> On both occasions, John was commander of the army that had to force the newly appointed shepherds to their faithful.<ref>Jansen (1979), p.&nbsp;31–32.</ref> The [[citizen]]s of [[Utrecht]] accepted the inevitable for the time being, but in Liège the unrest remained for many years, until in 1465 it came to an armed outburst. Again, John was part of the army that had to subdue the city liberties and in the [[Battle of Montenaken]] he was the commander of the victorious army division.<ref name="jansen32">Jansen (1979), p.&nbsp;32.</ref> He was also present at the at the capture of [[Dinant]] in August 1466.<ref name="blok1218" /> Even during the reign of Charles ‘the Bold’, John still was, despite his advanced age, often in the field.<ref name="jansen32" /> John's father had realised in time that the future lay with the Dukes of Burgundy; John drew the consequences and served the dukes faithfully, also by helping them to unscrupulously subdue city autonomy. This naturally benefited the position of his [[dynasty]], from which his son [[Engelbert II of Nassau|Engelbert&nbsp;II]] and grandson [[Henry III of Nassau-Breda|Henry&nbsp;III]] were to benefit. They rose so high in the favour of the dukes that they could actively influence politics.<ref name="jansen32" /> [[File:Siegen Schloss - 20.3.2011 - panoramio (1).jpg|thumb|left|Siegen Castle in 2011.]] [[File:Vianden castle.jpg|thumb|left|Vianden Castle.

The Rhine tolls had always been an important concern for the Counts of Nassau, because the [[iron]] [[trade]] and the exchange of vital goods with the Netherlands took place over the [[Rhine]].<ref name="luck26">Lück (1981), p.&nbsp;26.</ref> Approximately midway between their possessions in the Netherlands and their counties in Germany the Counts of Nassau owned a house in the city of Cologne (‘''das achte Haus von der Goltgassenecken nach St. Cunibert hin''’), which made the connection between the two areas easier for them. His widespread possessions forced John to travel constantly, in order to govern his possessions well. When John was in his county, he governed it from [[Siegen]] or [[Dillenburg]].<ref name="luck24">Lück (1981), p.&nbsp;24.</ref> The increasing [[Burgher (social class)|citizenry]] in the city of Siegen was a thorn in John’s side, but he did not succeed in enforcing any special rights there.<ref name="luck26" /> Siegen’s [[Town privileges|city privileges]] were co-granted by John’s ancestor Count [[Henry I, Count of Nassau-Siegen|Henry&nbsp;I of Nassau-Siegen]] in 1303.<ref name="luck21">Lück (1981), p.&nbsp;21.</ref> The County of Nassau-Siegen was divided into districts (''Ämter''). In each district (''Amt'') the count appointed an ''Amtmann''. These were members of the local [[nobility]] and deputised for the count. They had a number of servants to guard the public order. In times of [[war]] they formed the core of the army. Because of John's sometimes long absences, these ''Amtmänner'' had unlimited power.<ref name="becker28">Becker (1983), p.&nbsp;28.</ref> One of these was Philipp von Bicken, appointed by John. During John’s long absence, however, von Bicken used the trust placed in him and his own power base in the [[Haiger|Haiger Mark]] to repeatedly overstep his authority, to such an extent that he arrogated [[Territorial lord|territorial lord rights]] to himself, in order to increase his family’s still very considerable possessions. He fell into disfavour with John in 1466 and von Bicken fled the county and put himself under [[Landgraviate of Hesse|Hessian]] protection. It was not until 1486 that John’s son [[John V, Count of Nassau-Siegen|John&nbsp;V]] was able to definitively subjugate the {{Interlanguage link multi|von Bicken Family|de|3=Bicken (Adelsgeschlecht)}}.<ref name="becker14">Becker (1983), p.&nbsp;14.</ref> For the administration of [[justice]], the county had a ''[[Schultheiß]]'' in most of the districts. The oldest preserved ordinance for the ''Schultheiß'' of the Dillenburg district is from 10&nbsp;April 1465, which contains only a part of his tasks and authority. In this ordinance the provisions on [[matrimonial law]] are prominently present.<ref name="becker26">Becker (1983), p.&nbsp;26.</ref> The ''Reichshofgericht'' in [[Rottweil]] was competent for [[appeal]]s. For the ''Blutgerichtsbarkeit'' (high jurisdiction) the ''Hochgericht'' was competent. The [[Ewersbach|Ebersbach]] district had its own ''Hochgericht auf dem Stein''. During the [[execution]]s there, the count occasionally wielded the [[sword]] himself in order to [[Decapitation|behead]] the criminals. But mostly he left that to the [[executioner]]s. Also the other punishments and [[Fine (penalty)|fines]], which the count himself imposed in special cases, to give an example, were not insignificant for the monetary value of the time.<ref name="becker27">Becker (1983), p.&nbsp;27.</ref> When the count’s family started staying in the county more often, a [[Royal court|court]] was established. The financial administration was still relatively simple; there was no distinction between the public and the private [[treasury]] of the count. All income flowed into the private treasury of the count. The count received the revenues from the [[farm]]s in the [[village]]s [[in kind]], which were supplied by the [[serf]]s working there.<ref name="becker28" /> With the increase in [[Coins|coinage]], which resulted in payments in kind being increasingly replaced by payments in money, the office of ''{{Interlanguage link multi|Rentmeister|de|3=Rentamt|lt=Rentmeister}}'' became more and more important. The count’s fixed income included the ''{{Interlanguage link multi|Bede (tax)|de|3=Bede|lt=Mai und Herbst Bede}}'', which were levied on [[land tenure]]. There was also the ''Leibbede'', a [[personal tax]], which was levied when the serf died and had to be paid by his relatives. This originally consisted of the best piece of [[livestock]], but was later replaced by a sum of money. Finally, there was a [[hearth tax]], which had to be paid during [[Lent]]. The irregular revenues of the count included first of all the so-called ''Schatzungen'', [[tax]]es for special expenses and emergencies. Then there was the income from tolls, which were often [[lease]]d to subjects. This also applied to fishing rights, which the count owned. Taxes were also levied in the cities, on [[house]]s, [[garden]]s, [[Field (agriculture)|fields]] and [[meadow]]s.<ref name="becker29">Becker (1983), p.&nbsp;29.</ref> A not inconsiderable source of income for the Counts of Nassau has always been the iron toll. A [[charter]] of 1&nbsp;April 1470 concerning the [[tariff]]s in Siegen, [[Netphen]] and [[Wilnsdorf]] lists the individual taxes for [[pig iron]], [[steel]], [[cast iron]] pans, metal sheets, [[scythe]]s, [[cauldron]]s, etc. in detail.<ref name="luck61">Lück (1981), p.&nbsp;61.</ref> The expenses included the travels of the count and his family, celebrations at court, the [[remuneration]] of officials, court [[clothes]], [[altar candle]]s and [[Sacramental wine|communion wine]], but especially the workmen and materials for construction work at the various [[castle]]s.<ref name="becker30">Becker (1983), p.&nbsp;30.</ref> John had [[Dillenburg Castle]] –&nbsp;which until then had been used primarily as a [[stronghold]] against the unruly local nobility&nbsp;– extended in the period 1453–1467 and rebuilt into a residential castle for the count’s family.<ref name="becker31">Becker (1983), p.&nbsp;31.</ref> On 28&nbsp;May 1470, [[Holy Roman Emperor|Emperor]] Frederick&nbsp;III confirmed and granted John permission to purchase rights to the toll in [[Königsdorf (Frechen)|Königsdorf]] and the associated tolls in [[Mülheim]], {{Interlanguage link multi|Brück (Köln)|de|3=Brück (Köln)|lt=Brück}}, {{Interlanguage link multi|Lövenich (Köln)|de|3=Lövenich (Köln)|lt=Lövenich}}, {{Interlanguage link multi|Widdersdorf (Köln)|de|3=Widdersdorf (Köln)|lt=Widdersdorf}}, [[Bocklemünd]], {{Interlanguage link multi|Merheim|de|3=Merheim}} and {{Interlanguage link multi|Blatzheim|de|3=Blatzheim}}, as well as other rights from the [[Archdiocese of Cologne]]. The late Archbishop Thierry&nbsp;II had transferred these tolls and rights to John, with the approval of the [[Chapter (religion)|Chapter]], as [[Financial compensation|compensation]] for the losses caused by the Archbishop and the Archdiocese. This was evident to the Emperor from the copies of four charters signed by Thierry, which were presented to him, granting John the rights to these tolls and rights, which he still owned and had been using up until then, for the unhindered use of himself and his heirs.<ref>[http://www.regesta-imperii.de/id/1470-05-28_1_0_13_5_0_10835_211 RI XIII H. 5 n. 211] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> John was one of the princes ordered by the Emperor on 12&nbsp;June 1470 to wage war against [[Count palatine]] [[Frederick I, Elector Palatine|Frederick&nbsp;I]].<ref>[http://www.regesta-imperii.de/id/1470-06-12_1_0_13_4_0_10076_504 RI XIII H. 4 n. 504] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> John had the confidence of the Emperor. This is shown by the fact that in 1472 the Emperor ordered John to [[Interrogation|question]] [[witness]]es as his commissioner in the [[lawsuit]] in the ''Kammergericht'' between the citizens of {{Interlanguage link multi|Nauborn|de|3=Nauborn}} and the city of [[Wetzlar]]. In a [[summons]] to the ''[[Schultheiß|Schöffen]]'' of Wetzlar –&nbsp;sent by Count [[Philip II, Count of Nassau-Weilburg|Philip&nbsp;II of Nassau-Weilburg]] with John’s [[Power of attorney|letter of attorney]]&nbsp;– the [[Hearing (law)|hearings]] are mentioned to take place on 12&nbsp;October in Siegen.<ref>[http://www.regesta-imperii.de/id/1472-09-24_1_0_13_8_0_12337_329 RI XIII H. 8 n. 329] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> And on 30&nbsp;June 1474, the Emperor informed the [[mayor]]s and the city council of Cologne that he would soon pay off part of his [[debt]] of 2,000&nbsp;[[Rhenish gulden|Rhenish guilders]] by having John pay them the sum of 600&nbsp;guilders.<ref>[http://www.regesta-imperii.de/id/1474-06-30_1_0_13_7_0_11573_408 RI XIII H. 7 n. 408] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> John also seems to have been on the best of terms with the church. In any case, he received a so-called ''Butterbrief'' from [[Pope Sixtus&nbsp;IV]] (dated [[Rome]] 25&nbsp;February 1472), which allowed the inhabitants of his cities and castles to consume [[butter]] during Lent, and milk food –&nbsp;apart from [[cheese]]&nbsp;– instead of oil, because they lived in a cold region, where no [[olive oil]] grew and hardly any [[Fish as food|fish]] was available.<ref name="becker30" /> [[File:Bernaert van Orley (Netherlandish - Johan IV van Nassau and His Wife Maria van Loon-Heinsberg - Google Art Project.jpg|thumb|Count John&nbsp;IV of Nassau-Siegen and his wife Countess Mary of Loon-Heinsberg.

At John’s request, Emperor Frederick&nbsp;III declared on 28&nbsp;May 1470 that by granting the entire Duchy of Jülich to Duke [[Gerhard VII, Duke of Jülich-Berg|Gerhard&nbsp;VII]], the claims of Philippa of Loon-Heinsberg and her sister Mary, John’s wife, were not to be affected.<ref>[http://www.regesta-imperii.de/id/1470-05-28_3_0_13_0_0_6036_6037 Chmel n. 6037] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> Apparently this had no effect, because in 1471 or 1472 the Emperor ordered Duke Charles ‘the Bold’ of Burgundy to settle on his behalf the dispute between Gerhard on the one hand and John and his wife Mary on the other.<ref>[http://www.regesta-imperii.de/id/1471-00-00_1_0_13_5_0_10861_237 RI XIII H. 5 n. 237] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> In 1474, the Emperor withdrew the order to Charles ‘the Bold’ and instead transferred the matter to Archbishop [[John II of Baden|John&nbsp;II]] of Trier.<ref>[http://www.regesta-imperii.de/id/1474-00-00_1_0_13_5_0_10880_256 RI XIII H. 5 n. 256] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> However, the dispute was only settled when on 25&nbsp;August 1499 John’s son Engelbert&nbsp;II transferred his half of the castle and the land of Millen with the towns of Gangelt and Vught to Duke [[William IV, Duke of Jülich-Berg|William of Jülich and Berg]] and received in exchange from the latter on 27&nbsp;August 1499 the city and the land of [[Diest]] and the castle and the land of [[Zichem]] and [[Zeelhem]].<ref>Van der Eycken (1980), p.&nbsp;17–18.</ref> ===Dispute with his sister=== John came into conflict with his sister Mary. She filed a complaint against her brother with Emperor Frederick&nbsp;III for forcibly removing her [[inheritance]] and goods. On 14&nbsp;October 1463, the Emperor appointed [[Abbot]] {{Interlanguage link multi|Reinhard of Weilnau|de|3=Reinhard von Weilnau|lt=Reinhard}} of [[Princely Abbey of Fulda|Fulda]] as his [[Attorney-in-fact|attorney]] and instructed him to summon both parties to a trial on his behalf, to interrogate them and to give [[Judgment (law)|judgment]]. The abbot could –&nbsp;if necessary&nbsp;– examine witnesses and –&nbsp;if necessary&nbsp;– threaten these witnesses with punishment in order to force them to [[Testimony|testify]], as well as to carry out the proceedings in all respects in the event that one of the parties did not appear. The abbot summoned John by letter of 17&nbsp;August 1464 to appear before him 45&nbsp;days later in [[Bad Soden-Salmünster|Salmünster]]. John received this summons on 2&nbsp;September 1464 in [[Vianden]] from the hands of the ''servus et nuncius'' of the abbot.<ref>[http://www.regesta-imperii.de/id/1463-10-14_1_0_13_5_0_10773_149 RI XIII H. 5 n. 149] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> The abbot’s judgment is unknown, as is what happened next. As on 7&nbsp;July 1465, the Emperor informed Mary that John had appealed against the judgment by Archbishop John&nbsp;II of Trier unfavourable to him, and summoned her to appear before him on the 45th day after receipt of this summons or on the first day of the following court and informed her that, even if she did not appear, the trial would take place.<ref>[http://www.regesta-imperii.de/id/1465-07-07_1_0_13_5_0_10782_158 RI XIII H. 5 n. 158] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> What happened afterwards is also unclear. What is known is that the Emperor summoned John for the settlement of the inheritance dispute with his sister, because on 9&nbsp;February 1467 Mary appointed attorneys for the trial.<ref>[http://www.regesta-imperii.de/id/1467-02-09_1_0_13_8_0_12259_251 RI XIII H. 8 n. 251] in: [http://www.regesta-imperii.de/startseite.html Regesta Imperii Online].</ref> That is the last preserved record of the dispute. ===Last years, death, funeral and succession=== John signed an inheritance treaty with his sons on 4&nbsp;May 1472, in which it was decided to divide the possessions after John’s death. The eldest son, Engelbert&nbsp;II, would get the possessions in the Netherlands, while the youngest son, John&nbsp;V, would get the possessions right of the River Rhine (Nassau-Siegen and Diez).<ref name="huberty" /><ref name="becker13">Becker (1983), p.&nbsp;13.</ref><ref name="luck27">Lück (1981), p.&nbsp;27.</ref> John died in Dillenburg on 3&nbsp;February 1475<ref name="ditzhuyzen151" /><ref name="schutte41" /><ref name="dek69" /><ref name="blok1218" /><ref name="vorsterman93" /><ref name="vanderaa" /><ref name="becker13" /><ref>Wenzelburger (1881), p.&nbsp;252.</ref> and was buried under the grave monument in the ''[[Grote Kerk (Breda)|Grote Kerk]]'' in Breda.<ref name="blok1219" /><ref>Toebosch (1996).</ref><ref>Van Raak (1995), p.&nbsp;8.</ref><ref group="note">The sources do not mention a date of burial.
