[1] He also served as Othon 's aide, undertaking to deal with the movement of 3 September 1843, as well as the rebellion of his brother, Theodoros Grivas.

[2][3] He belonged to the historical family of the Grivai, for which there are references as early as 300 years before the revolution (around 1500) and which was a branch of the Albanian Bua tribe.

[5] His father, a former charioteer of Vonitsis and Xiromero, was poisoned by Ali Pasha, because he did not want to move against the village of Gardiki.

He particularly distinguished himself in the battle of Arachova (18-14 November 1826), when, sent by Karaiskakis to block the crossing of the Ottoman forces, he managed to enter the city with Georgios Vagias and 500 men first and occupy the most fortified positions, before the arrival of the Turkish forces.
