After being allied with Iraq during the Iran–Iraq War (largely due to desiring Iraqi protection from Iran), Kuwait was invaded and annexed by Iraq (under Saddam Hussein) in August 1990. Hussein's primary justifications included a charge that Kuwaiti territory was in fact an Iraqi province, and that annexation was retaliation for "economic warfare" Kuwait had waged through slant drilling into Iraq's oil supplies. The monarchy was deposed after annexation, and an Iraqi governor installed.
