When his motion was defeated, de Valera resigned from Sinn Féin; on 16 May 1926, he founded his own party,

Fianna Fáil came to power at the 1932 general election (to begin what would be an unbroken 16-year spell in government) and went on to long dominate politics in the independent Irish state.

At the 1955 United Kingdom general election, two Sinn Féin candidates were elected to Westminster, and likewise, four members of Sinn Féin were elected to Leinster House in the 1957 Irish general election. In December 1956, at the beginning of the IRA's Border Campaign (Operation Harvest), the Northern Ireland Government banned Sinn Féin under the Special Powers Act; it would remain banned until 1974. By the end of the Border campaign five years later, the party had once again lost all national representation. Through the 1960s, some leading figures in the movement, such as

and the Parliament of the United Kingdom was put before the members at the party's ''Ard Fheis''. A similar motion had been adopted at an IRA convention the previous month, leading to the formation of a Provisional Army Council by Mac Stíofáin and other members opposed to the leadership. When the motion was put to the ''Ard Fheis'', it failed to achieve the necessary two-thirds majority. The Executive attempted to circumvent this by introducing a motion in support of IRA policy, at which point the dissenting delegates walked out of the meeting. These members reconvened at Kevin Barry Hall in

It also declared itself opposed to the ending of abstentionism, the drift towards "extreme forms of socialism", the failure of the leadership to defend the nationalist people of Belfast during the 1969 Northern Ireland riots, and the expulsion of traditional republicans by the leadership during the 1960s. At its October 1970 ''Ard Fheis'', delegates were informed that an IRA convention had been held and had regularised its structure, bringing to an end the 'provisional' period. By then, however, the label "Provisional" or "Provo" was already being applied to them by the media. The opposing, anti-abstentionist party became known as "Official Sinn Féin". It changed its name in 1977 to "Sinn Féin—The Workers' Party", and in 1982 to " The Workers' Party". Because the "Provisionals" were committed to military rather than political action, Sinn Féin's initial membership was largely confined, in Danny Morrison's words, to men "over military age or women".

In particular, Ó Brádaigh's part in the 1975 IRA ceasefire had damaged his reputation in the eyes of northern republicans.

(SDLP). By 1985 it had 59 seats on seventeen of the 26 Northern Ireland councils, including seven on Belfast City Council. The party began a reappraisal of the policy of abstention from the Dáil. At the 1983 ''Ard Fheis'' the constitution was amended to remove the ban on the discussion of abstentionism to allow Sinn Féin to run a candidate in the forthcoming European elections. However, in his address, Adams said, "We are an abstentionist party. It is not my intention to advocate change in this situation." A motion to permit entry into the Dáil was allowed at the 1985 ''Ard Fheis'', but did not have the active support of the leadership, and it failed narrowly. By October of the following year an IRA Convention had indicated its support for elected Sinn Féin TDs taking their seats. Thus, when the motion to end abstention was put to the ''Ard Fheis'' on 1 November 1986, it was clear that there would not be a split in the IRA as there had been in 1970. The motion was passed with a two-thirds majority. Ó Brádaigh and about twenty other delegates walked out, and met in a Dublin hotel with hundreds of supporters to re-organise as Republican Sinn Féin.

On 2 September 2006, Martin McGuinness publicly stated that Sinn Féin would refuse to participate in a shadow assembly at Stormont, asserting that his party would only take part in negotiations that were aimed at restoring a power-sharing government. This development followed a decision on the part of members of Sinn Féin to refrain from participating in debates since the Assembly's recall the previous May. The relevant parties to these talks were given a deadline of 24 November 2006 to decide upon whether or not they would ultimately form the executive.

The Northern Bank robbery of £26.5 million in Belfast in December 2004 further delayed a political deal in Northern Ireland. The IRA were widely blamed for the robbery although Sinn Féin denied this and stated that party officials had not known of the robbery nor sanctioned it. Because of the timing of the robbery, it is considered that the plans for the robbery must have been laid whilst Sinn Féin was engaged in talks about a possible peace settlement. This undermined confidence among unionists about the sincerity of republicans towards reaching agreement. In the aftermath of the row over the robbery, a further controversy erupted when, on

Trends

Sinn Féin returned to Northern Ireland elections at the 1982 Assembly elections, winning five seats with 64,191 votes (10.1%). The party narrowly missed winning additional seats in Belfast North and Fermanagh and South Tyrone. In the 1983 UK general election eight months later, Sinn Féin increased its support, breaking the six-figure vote barrier in Northern Ireland for the first time by polling 102,701 votes (13.4%). Gerry Adams won the Belfast West constituency, and Danny Morrison fell only 78 votes short of victory in Mid Ulster. The 1984 European elections proved to be a disappointment, with Sinn Féin's candidate Danny Morrison polling 91,476 (13.3%) and falling well behind the SDLP candidate

. By the beginning of 1985, Sinn Féin had won its first representation on local councils, owing to three by-election wins in Omagh (Seamus Kerr, May 1983) and Belfast (Alex Maskey in June 1983 and Sean McKnight in March 1984). Three sitting councillors also defected to Sinn Féin in Dungannon, Fermanagh and Derry (the last defecting from the SDLP). Sinn Féin succeeded in winning 59 seats in the 1985 local government elections, after it had predicted winning only 40 seats. However, the results continued to show a decline from the peak of 1983, as the party won 75,686 votes (11.8%). The party failed to gain any seats in the 1986 by-elections caused by the resignation of unionist MPs in protest at the

. While this was partly due to an electoral pact between unionist candidates, the SF vote fell in the four constituencies they contested. In the 1987 general election, Gerry Adams held his Belfast West seat, but the party failed to make breakthroughs elsewhere and overall polled 83,389 votes (11.4%). The same year saw the party contest the Dáil election in the Republic of Ireland; however, it failed to win any seats and polled less than 2%. The 1989 local government elections saw a drop in support for Sinn Féin. Defending 58 seats (the 59 won in 1985, plus two 1987 by-election gains in West Belfast, minus three councillors who had defected to Republican Sinn Féin in 1986), the party lost 15 seats. In the aftermath of the election, Mitchell McLaughlin admitted that recent IRA activity had affected the Sinn Féin vote. In the 1989 European election, Danny Morrison again failed to win a seat, polling at 48,914 votes (9%). The nadir for SF in this period came in 1992, with Gerry Adams losing his Belfast West seat to the SDLP, and the SF vote falling in the other constituencies that they had contested relative to 1987.
