There are two main point of divergence with this timeline. First, the last Roman-Sassanid War that brought both empires to ruin was fought from 430 to 452. Secondly, instead of going to Britain, the Angles, the Saxons, and the Jutes migrated to Egypt late in the 5th century. The first Germanic kingdom on the Nile basin was Jutia, founded sometime in the early 6th century. By the time of the Arab invasion in 639, there were seven Germanic kingdoms in the former Roman province. Three major ones, Westrosettia in the west, Essex in the east, and Mercia in the south, and four minor ones, Wessex, Sussex, Jutia, and Middle Anglia. These seven kingdoms successfully repelled the Arabs and halted the spread of Islam. In the middle of the 9th century, King Alfred of Essex united all the English kingdoms into the Kingdom of England, and moved his capital to Alexandria. In 1053, the Vandalish lord Robert of Utica defeated Edward Haroldson and became the king of England, establishing the lineage of kings and queens that still exists today. In the 12th and 13th centuries, English kings conquered Coptic lands upstream to Swenett and established the principality of Wales, which would be annexed into England in the 16th century. From the 12th to the 16th centuries, English kings conquered Syrian lands, forming the Lordship of Syria. Meanwhile in 1273, King David of Alodia and Makuria united his kingdoms and became King David I of Nubia. From the 16th century, the kings of England allowed Jews to migrate to Palestine, under the belief that they would be more loyal than the Arabs. After Queen Audrey I died without an heir in 1613, her distant cousin, King David V of Nubia became King David I of England. This personal union eventually led to the Act of Union in 1710, founding the Kingdom of Egypt, and uniting the parliaments at Alexandria and Soba into one parliament based in Alexandria. A similar act in 1798 established the United Kingdom of Egypt and Syria. This union would not last more than a little over a century. The Syrian War of Independence, following the end of the First World War, saw the de facto independence of the Syrian Free State in 1922 as per the Treaty of Damascus. The Muslims were split though most wanted independence. The Druze, Maronites, and Alawites sided with the independence faction. The Jews sided with the UK. In 2022, Queen Audrey II died and King Benjamin III succeeded her.
