After the midterms, Congress would substantially break with Johnson and begin their first attempt at impeachment against him in January 1867, by which point Johnson’s practical trifecta was gone though he was still a National Unionist for the remainder of the term.</ref> |

Party divisions of United States Congresses have played a central role on the organization and operations of both chambers of the United States Congress—the Senate and the House of Representatives—since its establishment as the bicameral legislature of the Federal government of the United States in 1789. Political parties had not been anticipated when the U.S. Constitution was drafted in 1787, nor did they exist at the time the first Senate elections and House elections occurred in 1788 and 1789. Organized political parties developed in the U.S. in the 1790s, but political factions—from which organized parties evolved—began to appear almost immediately after the 1st Congress convened. Those who supported the Washington administration were referred to as "pro-administration" and would eventually form the Federalist Party, while those in opposition joined the emerging Democratic-Republican Party.[1]
Party divisions by Congress
[edit]The following table lists the party divisions for each United States Congress. Note that numbers in boldface denote the majority party at that particular time while italicized numbers signify a Congress in which the majority party changed intra-term.

- ^ The Anti-Administration Party was not a formal political party but rather a faction opposed to the policies of Treasury Secretary Alexander Hamilton. The faction eventually coalesced into the Democratic-Republican Party.
- ^ The Pro-Administration Party was not a formal political party but rather a faction supportive of the policies of Treasury Secretary Alexander Hamilton. The faction eventually coalesced into the Federalist Party.
- ^ a b Though Washington never formally joined a party, he was broadly sympathetic to what was later called the “Pro-Administration” faction which later became the Federalist Party.
- ^ Washington disapproved of formal political parties and refused to join either party, though he became a symbol of the Federalist Party.
- ^ a b When Democratic-Republican Thomas Jefferson began his Presidency in March 1801 the Senate held a two-day special Senate session with an ongoing Federalist majority, which briefly stalled the inauguration of a Democratic-Republican trifecta government, though the session was only called by outgoing President John Adams so that the Senate could provide advice to the new President. By the time the Congress began its first regular session in December 1801 to start official business the Democratic-Republicans had gained the Senate majority and thus, with the House and with President Jefferson, held the full trifecta of government throughout that first session and for the next several years.

- ^ a b c d The Democratic-Republican Party broke up into two competing parties during the 1820s, but there is no official date of dissolution for the Democratic-Republicans. During the presidency of John Quincy Adams, Congress became divided between a group that favored Adams and a group that favored Andrew Jackson. After Adams left office, Congress was divided into a group that supported the Jackson administration and a group that opposed it. During Jackson's presidency, the pro-Jackson group coalesced into the Democratic Party, while the anti-Jackson group (which included the National Republican Party) joined with the Anti-Masonic Party and other groups to form the Whig Party.
- ^ Adams won election as a Democratic-Republican, but he sought re-election as a National Republican.
- ^ Jacksonian control of the Senate was through plurality.
- ^ Jackson had a trifecta through a Senate that was controlled by plurality.
- ^ In the first Congressional session the Senate remained under control of “National Republicans” for one year; before the start of the second Congressional session the Senate reverted to Jacksonian control, and Jacksonians kept the Senate for the remainder of the Congressional term.
- ^ Jackson did not have a trifecta during the first Congressional session when the Senate remained under control of “National Republicans” for one year; Jacksonians flipped the Senate before the second Congressional session and Jackson held a trifecta through that new Senate majority for the remainder of the Congressional term.
- ^ Whig President William Henry Harrison died April 4, 1841, one month into his term, and was succeeded by John Tyler, who served for the remainder of the term. Tyler had been elected as vice president on the Whig ticket, but he became an independent after the Whigs expelled him from the party on September 13, 1841.
- ^ Whigs held their only trifecta from March 4, 1841, until later that year when the Whigs expelled Tyler from the party on September 13 and he became an Independent.
- ^ Whigs controlled the House through a plurality in the 2nd half of the 1st Congressional session; for the remainder of the two sessions the Whigs controlled the House through a majority.
- ^ The Democrats held the House through a plurality.
- ^ President Taylor died July 9, 1850, about one year and four months into the term, and was succeeded by Millard Fillmore, who served for the remainder of the term.
- ^ The "Opposition Party" was the congressional coalition formed by former Whigs and members of the nascent Republican Party. The Opposition Party opposed the Democratic Party in the aftermath of the collapse of the Whig Party.
- ^ The Republicans controlled the House through a coalition with other Opposition parties.
- ^ President Lincoln was assassinated and died April 15, 1865, about a month after beginning his second term as president. He was succeeded by Democrat Andrew Johnson, who served the remainder of the term.
- ^ The Republicans controlled the House through a coalition with Unconditional Unionists.
- ^ The Republicans held a trifecta by controlling the House through a coalition with Unconditional Unionists.
- ^ Johnson was elected as vice president on the National Union ticket, but was a Democrat prior to the 1864 election.
- ^ a b While Lincoln’s successor President Andrew Johnson, elected through the Republican-aligned National Union Party after formerly being a War Democrat, and the Republican Congress were on good terms and cooperated the first few years of his presidency, the relationship grew increasingly strained due to Johnson’s disagreements with Radical Republicans over the nature of Reconstruction. After the midterms, Congress would substantially break with Johnson and begin their first attempt at impeachment against him in January 1867, by which point Johnson’s practical trifecta was gone though he was still a National Unionist for the remainder of the term.
- ^ Republicans controlled the Senate through the tie-breaking VP.
- ^ Democrats controlled the House through a coalition with Independent Democrats.
- ^ a b When the Congressional term began with a special Senate session starting March 1881, the Republicans held the Senate (and a trifecta) through the tie-breaking Vice President Arthur and through a caucus that included a Readjuster Senator. When both Republican New York senators resigned on May 16 of that year, the Republicans lost control of the Senate and lost their trifecta, and the Senate ended their special session. By the time the Senate reconvened for a second special Senate session in October 1881 with two new Republican New York senators, Vice President Arthur had succeeded to the Presidency and the Senate deadlocked in what is known as the "Great Senate Deadlock of 1881”. For the rest of the special session and for the remaining two regular Congressional sessions, the Senate decided to give Republicans the role of controlling the all-too important Senate committees, give the Democrat-caucusing Independent the mostly ceremonial role of president pro tempore, and leave the patronage appointments and other Senate office appointments to the Democrats.
