History
The district was created in 1904 and named Bang Yai. Due to its size it was difficult to administer, and thus in 1917 the northern part was split off as minor district (king amphoe), Bang Mae Nang. In 1921 Bang Mae Nang became a full district.
On 19 October 1930 the district was renamed "Bang Kruai", after the geographic shape of district. Kruai is the Thai word for 'cone'. On the same date, Bang Mae Nang received the old name of the district, "Bang Yai".[1]
