Lithuanian Council of Lords

The Lithuanian Council of Lords (Lithuanian: Ponų taryba) was the main permanent institution of central government in the Grand Duchy of Lithuania active in its capital city of Vilnius.^[1]

It had originated from the advisory Council of the Grand Duke, established by Vytautas the Great in the early 15th century. During the reign of Casimir Jagiellon it was renamed to the Council of Lords. Under the Union of Lublin of 1569, the Council formally became a constituent part of the Polish–Lithuanian Senates (see also Offices in the Polish-Lithuanian Commonwealth), together with the Royal Council of Poland, but it continued to operate de facto until the mid-17th century.^[2][3]
