[3] In the 1920s and 1930s, Zazas played a key role in the rise of Kurdish nationalism with their rebellions against the Ottoman Empire and later the Republic of Turkey.
[19] Many Zazas subsequently joined the Kurmanji-speaking Kurdish nationalist Xoybûn, the Society for the Rise of Kurdistan, and other movements, where they often rose to prominence.
