Of these, 23 subsequently failed. Only two parties managed to return on their own (one failed again). One is represented as part of an electoral alliance. Some have merged with other parties, some have ceased to exist, and some maintain a twilight existence. We map and analyse the fate of parties that have fallen below the electoral threshold, and explore why some parties cease operations relatively quickly while others soldier on or maintain a 'zombie-like' existence. The core factors are the opportunity structures provided by other parties in terms of offers of alliances, mergers and/or new homes for the party elites; the existence of alternative arenas for competition than the national legislature (or national party lists); and the organisational strength of the party that falls below the threshold. is why we focus on these three particular countries. 1 In an earlier article in this journal (Bakke and Sitter 2013) we explained why parties in the Czech Republic, Slovakia, and Hungary failed to win re-election. 2 We concluded that small size and formal splits were the most important risk factors, and that (contrary to our expectations) participation in government as a junior partner primarily had an indirect effect: it tended to cause splits that led to failure, rather than lead directly to failure through loss of popularity. In addition several parties suffered from the declining salience of the political issues around which they were built (notably regional and nationalist parties), and a crowding-out effect from bigger and better managed competitors. We thus argued (in line with amongst others Harmel and Janda 1994, In the present article we ask what happened to the party organisation and the elites after the parties fell below the threshold, or more specifically why some parties become defunct within one election period of falling out, while others survive longer outside parliament. We suggest that death or survival depends on the strategic choices of the party elites, and on how these are shaped by institutional factors, the opportunity structure provided
