In GE13, the BN returned to power with a simple majority by winning 133 out of 222 parliamentary seats at stake to govern the country for an unbroken continuous period of 55 years.
(BN was previously known as Perikatan or Alliance before the coalition was enlarged).
Umno contributed 88 of the seats, nine more than GE12.
Founded by Datuk Onn Jaafar, who was the first Umno president, Umno was set up on May 11, 1946 to protest the Malayan Union mooted by the British government.
