Kurds
The Kurdish people are an ethnic group of Iranian descent who now mainly live in relatively large parts of Iran, Iraq, Turkey and Syria. The whole of this land was originally part of Safavid Iran, a large part of which (about 80% of the whole of Kurdistan) was ceded to the Ottoman government during the Chaldoran War of 1512-1520.
Of course, Kurd people are also scattered in other parts of the Middle East and Central Asia.
Most Kurds are Muslims and some of them are Yazidis, Parsans (Ahl al-Haqq), Christians and Jews.
Nowruz is an ethnic holiday among the Kurds. In Kurdish legends, the origin of this celebration is attributed to Kiomers king. The Kurds value religious customs and festivals such as Eid al-Adha, Eid al-Fitr, and especially the birth of the Prophet of Islam.
In a theory, the origins of the Kurdish tribes of Iran are considered to be a combination of the people of the Middle East and the Aryans living on the shores of the Caspian Sea, who then migrated to the Kurdistan region.
Kurdish is the root of Iranian languages before the Arab invasion of Iran. This dialect has not been much influenced from Arabic and Turkish and has remained more or less original.
