Why did North Yemen unify with South Yemen?

The idea of a united Yemen was promulgated by the Zaydī imamate after North Yemen’s independence in 1918 and subsequently promoted by other actors, especially Pan-Arabist republicans. Unification with South Yemen was made possible by Ali Abdullah Saleh’s consolidation of power, the crisis in South Yemen caused by a collapse of Soviet support, and the discovery of oil and natural gas in the border region.
