進歩党 (Shinpotō) was a political party in Japan, established in 1882. It aimed to promote democratic reforms and modernize the political system. The party was part of the broader movement towards democracy during the Meiji era, advocating for civil rights and the establishment of a parliamentary government. The party faced challenges, including internal divisions and opposition from more conservative factions. It eventually merged with other political groups, contributing to the formation of the 自由党 (Liberal Party) in 1889. The legacy of 進歩党 is significant in the context of Japan's political evolution and the development of democratic institutions.
