The culture of the Assyrians is both distinct from those of neighbouring ethnic groups as well as ancient. Many Assyrians (estimates of fluent speakers range from 500,000) still speak, read and write various Akkadian-influenced dialects of Eastern Aramaic, labelled by linguists as Northeastern Neo-Aramaic and Central Neo-Aramaic. They are predominantly adherents of several denominations of Syriac Christianity, notably the Ancient Church of the East, the Assyrian Church of the East, the Chaldean Catholic Church, the Syriac Catholic Church and the Syriac Orthodox Church. Some are followers of the Assyrian Pentecostal Church and Assyrian Evangelical Church. A minority are secular or irreligious.

Annual celebrations

Assyrians celebrate many different kinds of traditions within their communities, with the majority of Assyrian traditions being tied to Christianity. A number include feast days (Syriac: hareh) for different patron saints, the Rogation of the Ninevites (, Baʿutha d-Ninwaye), Ascension Day (Kalo d-Sulaqa), and the most popular, the Kha b-Nisan (, 'First of April'). Some of these traditions have been practised by the Assyrians for well over 1,500 years.

Yawma d-Sahdhe ('Martyrs Day')

Assyrian culture

The Simele massacre (, Pramta d-Simmele) was the first of many massacres committed by the Iraqi government during the systematic targeting of the Assyrians of northern Iraq in August 1933. The killing spree that continued among 63 Assyrian villages in the Dohuk and Nineveh districts led to the deaths of an estimated 3,000 Assyrians.

Assyrian culture

August 7 became known as Martyrs Day (, Yawma d-Sahdhe) or National Day of Mourning by the Assyrian community in memory of the Simele massacre as it was declared by the Assyrian Universal Alliance in 1970. In 2004, the Syrian government banned the Assyrian political organization and the Assyrian community of Syria from commemorating the event, and threatened arrests if any were to break the ban.

Resha d-Nisan ('Start of Spring' or 'Assyrian New Year')

The Assyrian new year festival, known as Resha d-Nisan (literally 'Head of April'), is celebrated on the first day of spring and continues for 12 days.

Celebrations involve holding parades and parties, gathering in clubs and social institutions and listening to poets reciting "the Story of Creation." The men and women wear traditional clothes and dance in parks for hours.

After the formation of the Turkish state in the 1920s, Resha d-Nisan along with the Kurdish Nowruz were banned from being celebrated in public. Assyrians in Turkey were first allowed to publicly celebrate Resha d-Nisan in 2006, after organisers received permission from the government to stage the event, in light of democratic reforms adopted in support of Turkey's EU membership bid.

Kalo d-Sulaqa ('Bride of the Ascension')

The legend of Kalo d-Sulaqa tells of a young Malik Shalita, governor of the Assyrian homeland's capital Mosul, who was first noticed by Tamerlane after he had successfully fought and defeated his initial attack on the city. The battle is then described as freedom fighters, both Christian and Muslim, defended against the Mongol attack.

It was during this time that, according to legend, Malik Shalita's wife organised Assyrian women dressed in white, and was given the responsibility to collect provisions from the nearby towns in order to feed the men fighting at the front. Having heard the fate that had befallen their countrymen in Tikrit and Mardin, they knew very well the fate in store for them if they were to lose this battle. Instead of running and hiding, the women prepared for the battle and joined the ranks of the defenders against unfavourable odds.

The historical account is in keeping with the legend, as both describe a brutal battle of attrition, in which both men and women joined and defended themselves against Tamerlane's attack. Malik Shalita and his wife—according to the legend dressed in white—are recorded as having been killed in this battle.

The Assyrian historian Arsanous states that the young boys and girls represent the dead young men and women who ascended to heaven because they died for the cause of Christianity and in defence of their homeland. The tragic nature of the 1401 event had left such an indelible impression on the minds of the survivors that they remembered the final battle and have honoured the memory of the fallen by re-enacting the camaraderie of the Assyrian men and women who died defending their homeland. However, those who managed to survive the massacres also in Baghdad were forced to flee into the Zagros Mountains.
