Starting with the first West German election in 1949, West Berlin sent a number of deputies (de) to the Bundestag. Under the terms of the Four Power Agreement on Berlin, West Berlin could not participate in West German federal elections, so instead the city's state parliament chose 22 non-voting "Berlin deputies" on the same date as elections were held in the rest of West Germany. These deputies were non-voting for most of West Berlin's history, but on 8 June 1990 they were given full voting right, increasing the voting membership of the Bundestag from 497 to 519. The 22 members elected in 1987 were broken down by party as follows: 11 from the CDU, 7 from the SPD, 2 from the FDP, and 2 from the Alliance 90/Green Party.
German reunification took place during this Bundestag. When East Germany was dissolved on 3 October 1990, 144 members of the Volkskammer were transferred to the Bundestag, who would sit until the next election along with the West German members elected in 1987. This increased the size of the Bundestag to 663. The 144 members were broken down by party as follows: 63 from the CDU, 33 from the SPD, 24 from the PDS, 9 from the BFD, 8 from the DSU, and 7 from Alliance 90/Green Party.
