Vaidila

Vaidila (Woidiło, Voydiło, Woydylo; executed in 1381) was a favorite and brother-in-law of Jogaila, Grand Duke of Lithuania.

The Lithuanian Chronicles present Vaidila as a kitchen assistant who rose to the top and entered the nobility only through his marriage to Jogaila's sister Maria in 1379.

[2] The Teutonic Knights mention that boyar Vaidila ruled Wegebeticht (believed to be near Deltuva) and Wayteldorff (Dubrowo, north of Lida).

Jogaila revenged his death by executing Vidimantas and his son Butrimas, relatives of Birutė, wife of Kęstutis.

[2] This marriage might be an indication that Jogaila needed domestic alliances to keep his throne after his father Algirdas died in 1377 and his elder brother Andrei of Polotsk challenged the last will.
