In May 1883, at the age of 13, Gandhi was married through his parents' arrangements to Kasturba Makhanji (also spelled "Kasturbai" or known as "Ba"). They had four sons: Harilal Gandhi, born in 1888; Manilal Gandhi, born in 1892; Ramdas Gandhi, born in 1897; and Devdas Gandhi, born in 1900. 
Harilal Mohandas Gandhi (1888- 18th June 1948) was the first son of Mahatma Gandhi. 
Mahatma would not allow his son to study law as a show of rebellion against a Western education  and Harilal eventually grew weary of this, and rebelled. Harilal converted to Islam and adopted the name "Abdullah Gandhi", but later again converted to Hinduism 

In Early years Harilal helped his father in revolution against British Government for their attitude about racism. He had always wanted to go for higher studies and wanted to become a barrister like his father, but because of his weakness in studies, he could not complete his high-school education.lost his wife and son. 

Failure in life made him a depressed alcoholic. He died because of a liver disease on June 18th, 1948 in a municipal hospital in Mumbai, known at the time as Bombay.
