(CNN) -- TP Mazembe claimed the African Champions League after beating Nigerian side FC Heartland 1-0 in the second leg of their final in Lubumbashi on Saturday, winning on away goals.
An own goal by Heartland defender Emmanuel Ompdiagbe after 73 minutes was enough to secure Mazembe their third African club championship title after they trailed 2-1 from last weekend's first leg.
It was the first win in the competition for a side from the Democratic Republic of Congo since Mazembe claimed successive titles in 1967 and 1968.
It qualifies Mazembe for December's FIFA Club World competition in the United Arab Emirates and nets them $1.5 million in prize money.
DR Congo President Joseph Kabila presented the victorious players of Les Corbeaux with the trophy after a tense second leg of few chances.
The closest the hosts came to breaking the deadlock came at the end of the first leg as Tresor Mputu Mabi, who scored the crucial away goal for Mazembe in Nigeria last weekend, found Kalauyituka Dioko, but his header was saved by Augustine Brown.
Mazembe pushed forward strongly in the second half and were aided by injuries to three key Heartland players, including goalkeeper Brown.
With 17 minutes remaining a fine run and cross by left-back Somwe Joel saw the unfortunate Omodiagbe head the ball past substitute goalkeeper Ikechukwu Ezenwa.
Heartland were reduced to 10 men late on as Emeka Nwanna was sent off for serious foul play.
The victory may signal the departure from Mazembe of the highly-rated Mputu Mabi, as the 24-year-old admitted after the historic win.
"I promised myself that I would have to guide the club to a great feat before I think about leaving," he told www.cafonline.
"Now, after winning the Orange CAF Champions League, I feel fulfilled," he added.
