The historical Armenian Evangelical Church (Turkish: "Ermeni Protestan Kilisesi" , Armenian: Հայաստանեայց Աւետարանական Եկեղեցի ) is an Armenian Evangelical church located in the centre of the Turkish town of Elâzığ (Mamuretül-Aziz), next to Kharpert.
 It was built in the 19th century and constituted the headquarters of this Church for Elazig.
 After the Armenian Genocide, the church was used as the "Arpaci" Powder Industry Fabrique, then as a playground for children, and marketplace and shelter for animals.
 Despite its Armenian identity it was described as an "historical Assyrian church" by the Turkish authorities in 1973.
 In 2007, the Turkish state announced it will turn the church into a hospital, but as of 2014 no change has been made.
 Because of its location in the centre of Elazig, it is used as parking lot for cars.

Taw Mim Semkath (Syriac: ܬܡܣ "T.M.S.", originally ܒܝܬ ܝܬܡܐ ܕܐܬܘܪܝܐ ܒܩܝܠܝܩܝܐ "Beth Yatme d-Othuroye b-Qiliqiya"), also known as Assyrian National School Association (ANSA) after its founding organisation, is an Assyrian school and orphanage that opened in Adana in 1919 for orphaned Assyrian children who survived the Assyrian genocide.
 The Assyrian National School Association, established in Stirling, New Jersey in 1899 by Assyrian immigrants from Diyarbakir who fled the massacre in 1895, founded the school with help from the French High Commissioner.
 The Syriac Orthodox bishop Yuhanon Dolabani was an important figure at the school, contributing a lot with teaching and organizing.
 In 1921, the school was closed by the Turkish authorities and moved to Beirut, Lebanon, where it is still running.
Ashur Yousif (born Abraham Yusef), (Syriac: ܐܫܘܪ ܝܘܣܦ ܐܦܢܕܝ) (1858 Harput, Ottoman Empire - June 23, 1915 Diyarbekir, Ottoman Empire) was a professor and an ethnic Assyrian intellectual prior to World War I and the Assyrian Genocide.
 He was Protestant, as was his wife - Arshaluys Oghkasian, daughter of an Armenian Protestant minister.
 He studied (but did not graduate) at the Central Turkey College in Antep, and later became professor of Classical Armenian language at the Euphrates College in Harput.
 In 1909, Ashur started publishing a Turkish-language newspaper named "Murshid Athuriyion" ("the spiritual guide of the Assyrians").
 He also composed poems in Armenian and Turkish.
Assyrian cuisine is the cuisine of the indigenous ethnic Assyrian people, Eastern Aramaic speaking Syriac Christians of northern Iraq, north eastern Syria, north western Iran and south eastern Turkey.
 Assyrian cuisine is very similar to other Middle Eastern cuisines such as Greek cuisine, Lebanese cuisine, Turkish cuisine, Israeli cuisine, Armenian cuisine and Persian cuisine, with most dishes being similar to the cuisines of the area in which those Assyrians live/originate from.
 It is rich in grains, meat, tomato, herbs, spices, cheese and potato.
 Alcohol, in particular Wheat Beer, Organic Wine and Arak is also consumed
A number of Christian militias have formed in Syria since the start of the Syrian Civil War in 2011.
 The militias are composed largely of fighters from the various Syriac, Assyrian, Arab and Armenian Christian communities in Syria, and are also found amongst Assyrian communities in neighbouring northern Iraq.
 Before the war, as much as 10% of the population was Assyrian, Syriac-Aramean, Armenian or Arab Christian, and together they formed one of the largest Christian minorities in the middle east.
 In the early days of the civil war, some Christian communities were armed by the Syrian Government and Kurds to defend themselves against what were seen as threatening sectarian Sunni Islamic rebels.
