Final answer:
The Persian Gulf War began after Saddam Hussein invaded Kuwait, seeking control over its oil reserves.
Step-by-step explanation:
The Persian Gulf War began after Saddam Hussein invaded Kuwait. After the Iran-Iraq War, Hussein sought to gain control over Kuwait's oil reserves and accused Kuwait of slant drilling oil wells along the Iraqi border. This invasion led to the First Persian Gulf War, which resulted in an international military coalition led by the United States launching an operation to remove Hussein's forces from Kuwait.
