Jordan was home to 2,175,491 Palestinian refugees as of December 2016; most of them, but not all, had been granted Jordanian citizenship. The first wave of Palestinian refugees arrived during the 1948 Arab–Israeli War and peaked in the 1967 Six-Day War and the 1990 Gulf War. In the past, Jordan had given many Palestinian refugees citizenship, however recently Jordanian citizenship is given only in rare cases. 370,000 of these Palestinians live in UNRWA refugee camps. Following the capture of the West Bank by Israel in 1967, Jordan revoked the citizenship of thousands of Palestinians to thwart any attempt to permanently resettle from the West Bank to Jordan. West Bank Palestinians with family in Jordan or Jordanian citizenship were issued yellow cards guaranteeing them all the rights of Jordanian citizenship if requested.
