A word “uhlan”, came to English through Polish. The etymological dictionaries of English wrongly derive uhlan from the Turkish oglan – “a young man”. In the Tatar of the epoch of the Golden Horde, uglan meant not only “a child, a young man”, but also “a noble warrior”, and was also applied in relation to the Khan’s Guards.
