Székely peasants moved across the Carpathians into Moldavia in order to escape the system of forced recruitment into the Austrian army and the 1764 massacre. Today they live mainly in about 30 locations in the Trotuș and Tazlău valleys, with a few in the Siret valley mixed with Moldavian Romanians. Their Hungarian dialect is close to that of the Székely and most are bilingual in the Moldavian dialect of Romanian.
About 70,000 Catholics live in these locations in Moldavia, of which 45,000 can speak Hungarian. One view is that they are all of Székely Hungarian ancestry, but have been subjected to Romanianisation, which can be seen in those speaking Moldavian Romanian.
The alternative view is that these Catholics who moved from Transylvania were a mix of Székely and Romanian origin. In all probability the Romanians would have been bi-lingual and can be distinguishable by their Transylvanian Romanian dialect.
|1479 – 1493||Many Székely escape to Moldavia, due to the cruelty of Transylvanian voivode István Báthory.|
|1764||Székely who had evaded recruitment into the Austrian army were gathered in Csíkmádéfalva. To prevent further insubordination 1,300 troops attacked them, in the early hours of 7th January, killing hundreds. The survivors of the massacre, together with others who were intimidated, escaped to Moldavia.|
