In 1888, Homeland Funds was renamed Ziraat Bankası (), and Ziraat Bank's head office in Istanbul began to function. The Greco-Turkish War between 1919 and 1922 affected the bank's policy. The Greek invasion forces opened a Ziraat Bank Management Center in İzmir and occupied branches and funds were taken to the new Center's management. On the other hand, the Turkish Grand National Assembly charged the Ankara branch of Ziraat Bank with the management of branches and funds. With the Liberation of İzmir by Turkish forces on September 9, 1922, the İzmir organization was re-unified with the Ankara branch; and on October 23, the Istanbul organization too was re-unified with the Ankara branch. After the Turkish War of Independence ended in late 1923, Ziraat Bank became a united entity once again. Since the 1930s Ziraat played an important role in financing agricultural mechanisation in Turkey, which in the postwar period benefitted from support from the US Marshall Plan.
