Disclaimer: This is NOT meant to incite political debate. I am looking for a historical answer.
Presidents George H W Bush and George W Bush both invaded the Middle East. Before these two, what father and son pair each invaded the Middle East while top-level political leaders of their land? Maybe during the crusades?
Clarification: The question is for the names of the father-son pair who invaded the Middle East prior to the Bush family. The best answer is the most recent.
If we're allowed to expand the definition of the "Middle East" (and possibly also "invasion") a little, Russian Tsar Nicholas I died on March 2, 1855 in the middle of the Crimean War, and his son Alexander II inherited the whole bloody farce, including a back-and-forth sideshow in the Caucasus, across the border between Georgia and Turkey.
After several incursions in both directions and much fumbling on both sides, the Russians managed to besiege the city of Kars in northeastern Turkey, but the siege dragged on until the Ottomans finally surrendered on November 8, 1855 after Alexander was crowned. Russia's only success in an otherwise complete humiliation, and the peace treaty made them give it back.
