|Started first in 1902.
Cities belonging to this congregation today:

The East-Danubian church is also called as the Unitarian Fellowship between the Danube and Tisza rivers.
It was first established in 1902 as a mission territory of the 9th district of the Hungarian Unitarian Church.
In 1920, after Trianon, when Transylvania was ripped away from Hungary, it remained an unorganized fellowship. But there was a lay person, P. Buzogány Lajos in Kecskemét, who took care of Unitarian youth education.
From 1929 the ministers from the Budapest Mission House took care of religious life. They visited the members and held Sunday services.
The first meeting after the church was officially established was held in 1944, when the congregation elected two lay presidents: P. Buzogány Lajos in Kecskemét and H. Fejér Domokos in Rákospalota. They still had no local minister, and the ministers from the Mission House continued to act as supply until 1951.
The fellowship extended to the following cities: Kecskemét, Szolnok, Rákospalota, Újpest, Sashalom, Rákosszentmihály, Gödöllő, Hatvan, Pestújhely, Zugló, and after 1946, more: Mátyásföld, Rákoshegy, Rákoskeresztúr, Rákosliget, Rákoscsaba.
In December 1975 the bishop sent the Rev. Kelemen Miklós to serve this fellowship. He had responsibility for the following cities: Kecskemét, Szolnok, Nagykörös, Cegléd and Hatvan.
At that time many of the small towns were incorporated into Budapest territory and became part of the Budapest churches.
Rev. Kelemen Miklós serves this church to this day, even though he is retired and lives in Budapest. But the church attendance is high, especially for major events and holidays. There are baptisms, confirmations, and an active church life. It does not have a building, the services are kept in other denomination’s buildings.
Today the diaspora includes the following cities: Kecskemét, Veresegyháza, Budakalász, Ladánybene and Ásotthalom.
After 1990, many Unitarians moved to Hungary from Transylvania, many settling in Kecskemét and the surrounding areas. These members had a need for church life, and today Kecskemét is the center of the diaspora.
