The Estates General of 1464 was a parliamentary assembly of representatives of the constituent territories of the Burgundian Netherlands (now parts of France, Belgium, Luxembourg and the Netherlands).
Each of the territories represented already had parliamentary institutions (provincial estates) of its own.
The convocation of a meeting of representatives of all of these territories was the initiative of the States of Flanders (between 20 and 24 December), followed by Philip the Good (on 25 December), and his son Charles the Bold (on 26 December).
Although in first instance reacting to the initiative of the States of Flanders, Duke Philip and his son were quick to adopt the convocation of the Estates General in support of their policy of centralizing their rule over their various territories.
