[1] Alongside other lower nobles from Eastern Hungary and Transtisia, for instance Michael Balogsemjén, Rubinus Hermán and Mizse, he committed to supporting the efforts of King Ladislaus IV ("the Cuman").

In order to eliminate the powerful barons' influence over the royal council, Ladislaus managed a self-coup in September 1286, expelling members of the Kőszegi–Borsa baronial group from the government body.

Neglecting the Kőszegis' rival, the Széplak branch of the Aba clan, represented by Amadeus and Peter, Makján's very distant relatives, Ladislaus IV appointed his own loyal soldiers and lesser nobles to the high positions.

However these titles were purely nominal as the rebellious and oligarchic Kőszegi family ruled de facto independently the western parts of Transdanubia, including the aforementioned three counties by then.

[7] It is plausible that Makján held his dignity until spring 1287, when the Kőszegi troops defeated Ladislaus' army at the river Zsitva (Žitava).
