It included the Polish People's Party "Piast" and an older coalition 1922 Christian Association of National Unity (Chrześcijański Związek Jedności Narodowej).
The Chjeno-Piast coalition was the political base of two consecutive governments formed by Wincenty Witos.
The first, formed in May 1923, antagonized Józef Piłsudski, who resigned his government posts blaming Chjeno-Piast for the assassination of Gabriel Narutowicz.
This government was forced to resign in December of that year in the effect of massive worker riots in Kraków.
The first part of the name of the coalition (being an abbreviation of Chrześcijańska Jedność Narodowa) resembles the Polish word hiena, meaning hyena.
