The gulf war started because Iraq invaded Kuwait in 1990 for a few reasons: One, Kuwait increased its oil production by 40%, and Iraqi government (Saddam Hussein )claimed that Kuwait had used its oil fields and that Kuwait had declared an economic warfare on Iraq; second, the British High Commissioners, when drawing borders for Iraq and Kuwait, had given Iraq little coastline while giving much more to Kuwait, restricting Iraq's access to Persian Gulf; third, Kuwait never officially seceded from the Ottoman empire, thus Iraq saw it as part of itself.
