On Friday, Donald Trump barred citizens of seven Muslim-majority countries – Iraq, Syria, Iran, Sudan, Libya, Somalia and Yemen – from entering the United States for at least the next 90 days.
He also suspended the US refugee programme for 120 days, specifically banning Syrian refugees until further notice, reduced the number of refugees who would be admitted this year to 50,000 and specified that refugees who were from a religious minority and fleeing religious persecution should be prioritised.
A federal judge has blocked part of Trump’s executive order, ruling that travellers who have already landed in the US with valid visas should not be sent back to their home countries, and protests in response to passport holders from some Arab countries, including US green card holders, being blocked from passing through customs or prevented from boarding US-bound planes, have taken place at airports across the country.
But this is not the first time that the US has banned immigrants from its shores. Over the past 200 years, successive American presidents have placed restrictions on the immigration of certain groups.
