Thailand

Date range: 1980-2020 (2006 and 2014 elections are not included, as both were boycotted and annulled).
Thailand has had a patchy history of democratization, with numerous democratic constitutions and elections overturned by military coups. The 1990s period of “semi-democracy” (in which the army controlled the executive but allowed legislative elections) is a questionable inclusion in the dataset, however we have concluded that these elections should be included (although no party from this era seemed to be sufficiently populist to warrant inclusion in the dataset).
