Xenophobia is the fear and distrust of that which is perceived to be foreign or strange. Xenophobia can manifest itself in many ways involving the relations and perceptions of an ingroup towards an outgroup, including a fear of losing identity, suspicion of its activities, aggression, and desire to eliminate its presence to secure a presumed purity. Xenophobia can also be exhibited in the form of an "uncritical exaltation of another culture" in which a culture is ascribed "an unreal, stereotyped and exotic quality".
The terms xenophobia and racism are sometimes confused and used interchangeably because people who share a national origin may also belong to the same race. Due to this, xenophobia is usually distinguished by opposition to foreign culture. Xenophobia is a political term and not a recognized medical phobia.
Dictionary definitions of xenophobia include: "deep-rooted fear towards foreigners" (Oxford English Dictionary; OED), and "fear of the unfamiliar" (Webster's). The word comes from the Ancient Greek words ξένος (xenos), meaning "strange", "foreigner", and φόβος (phobos), meaning "fear".
A scholarly definition of xenophobia, according to Andreas Wimmer, is "an element of a political struggle about who has the right to be cared for by the state and society: a fight for the collective goods of the modern state". In other words, xenophobia arises when people feel that their entitlement to benefit from the government is being subverted by other people's rights.
An early example of xenophobic sentiment in Western culture is the Ancient Greek denigration of foreigners as "barbarians", the belief that the Greek people and culture were superior to all others, and the subsequent conclusion that barbarians were naturally meant to be enslaved. Ancient Romans also held notions of superiority over all other peoples, such as in a speech attributed to Manius Acilius, "There, as you know, there were Macedonians and Thracians and Illyrians, all most warlike nations, here Syrians and Asiatic Greeks, the most worthless peoples among mankind and born for slavery."
United States of AmericaEdit
Democratic President Franklin Roosevelt displayed the Executive Office's concern over foreign nationals in the early to mid 1940's, this included Citizens of the United States through his implementation of Japanese Internment during World War 2. Sending US citizens to what president Roosevelt described as "Concentration Camps", showed the fear he and his party displayed towards US citizens of Japanese ancestry and is still one of the best examples of irrational fears associated with a specific non-native nationality.
After Republican candidate Donald Trump took presidential office in 2017, he repeatedly attempted to enact a travel ban on originally seven countries, later changed to six with amendments. The seven original Islamic countries were Iraq, Iran, Somalia, Sudan, Yemen, Syria and Libya although later "Iraq was removed from the list after criticism that the original order overlooked the country’s role in fighting Islamic terrorism and barred entry even to the Iraqi interpreters who had been embedded with US forces in the region" This move for a travel ban was described as xenophobic by Amnesty International  and the father of fallen United States Army Captain Humayun Khan, Khizr Khan described it in a CNN interview as a continuation of Trump's xenophobic rhetoric. 
Xenophobia in South Africa has been present in both the apartheid and post–apartheid eras. Hostility between the British and Boers exacerbated by the Second Boer War led to rebellion by poor Afrikaners who looted British-owned shops. South Africa also passed numerous acts intended to keep out Indians, such as the Immigrants Regulation Act of 1913, which provided for the exclusion of "undesirables", a group of people that included Indians. This effectively halted Indian immigration. The Township Franchise Ordinance of 1924 was intended to "deprive Indians of municipal franchise."
In 1994 and 1995, gangs of armed youth destroyed the homes of foreign nationals living in Johannesburg, demanding that the police work to repatriate them to their home countries. In 2008, a widely documented spate of xenophobic attacks occurred in Johannesburg. It is estimated that tens of thousands of migrants were displaced; property, businesses and homes were widely looted. The death toll after the attack stood at 56.
In 2015, another widely documented series of xenophobic attacks occurred in South Africa, mostly against migrant Zimbabweans. This followed remarks by Zulu King Goodwill Zwelithini kaBhekuzulu stating that the migrants should "pack their bags and leave". As of 20 April 2015, 7 people had died and more than 2000 foreigners had been displaced.
