Paolo Di Canio said Swindon winning the League Two title was the best moment of his career after his side defeated Port Vale 5-0.
Paul Benson scored twice and Matt Ritchie, Aden Flint and substitute Alan Connell were also on target as Swindon sealed the championship in style.
Proud Di Canio said: "As a player I won Serie A and the UEFA Cup but this is the best because it is my first trophy as a manager.
"It is not about the medal. It is about taking charge of a team and my players deserve a lot of credit. We have been the best team in the division all season and deserve to go up as champions."
Di Canio wore a T-shirt with pictures of his parents on the front as he led his players up to collect their winners' medal after both tragically passed away in the space of four months.
The Italian, who only took charge at the County Ground last summer, said: "I hope they are looking down on me and smiling. They were my inspiration. The last few weeks have been very difficult for me but I had to focus on my job and making sure we won the league."
