Quick Intro

A Lithuanian-origin princely magnate family that emerged from the Astikai line in the 15th century, achieved princely status in 1547, and became one of the dominant political, military, confessional, and cultural houses of the Grand Duchy of Lithuania and later the Polish-Lithuanian Commonwealth.

Origins & Ancestry

For database purposes, Kristinas Astikas is the safest documented ancestor. His son Radvila Astikaitis is the founder of the distinct Radvila line. Earlier descent from Sirputis and broader links to older Lithuanian dynastic traditions should be marked as probable or traditional rather than fully secure.

The Radvila line split from the Astikai family through Radvila Astikaitis, son of Kristinas Astikas.
