The Birka female Viking warrior was a woman buried in the 10th century in Birka, Sweden and discovered in the 1870s. The grave was assumed to be a battle hardened man for 128 years until DNA analysis proved she was actually a high-ranking professional warrior. Shield-maidens are female warriors that take on male roles including wielding weapons and are depicted in many period figures, tapestries and brooches as well as mentioned by the famous Danish historian of the time, Saxo Grammaticus.

The grave chamber was made of wood and approximately 3.45m long and 1.75m wide. The body was in a sitting position and found earing garments of silk and silver. The grave contained a sword, an axe, a spear, armor-piercing arrows, a battle knife, two shields, two horses, one mare and one stallion. The grave also contained a game set with a board and pieces. This is considered evidence of her strategic thinking and indicating she was an officer who could lead troops into battle.

In 1907, two mummies were discovered in Deir Rifeh Egypt in a tomb belonging to a governor and his sons from the 12th Dynasty (almost 4000 years ago). The tomb group is one of the best preserved and best known burials of the Egyptian Middle Kingdom. Although the mummies were heavily decayed, the skeletons were still preserved. Khnum-Nakht was about 40 years old and Nakht-Ankh about 60.

The two mummies were found to be brothers with the same mother but different fathers. This is confirmed by identical mtDNA and the detected differences in the Y chromosomes. Both suffered from osteoarthtritis and dental attrition. Khnum-Nakht had kyphoscoliosis and Nakht-Ankh had lung lesions from sand pneumoconiosis.

The Crusader States (also known as Outremer) were created after the First Crusade (1095-1102) as a way to keep hold of territorial gains by Christian armies in the Middle East. Crusader castles were built all over Outremer to serve not only as defensive structures, but also as administrative and economic centers designed to last for many years to come. The four small Outremer states were the Kingdom of Jerusalem, the County of Edessa, the Country of Tripoli and the Principality of Antioch. This analysis focuses on the former Phoenician and later Roman colony of Sidon / Saida which remained in Arab hands until 1110 when King Baldwin I of Jerusalem and King Sigured I of Norway captured it. The city was then re-captured by the masterful Saladin in 1187, only to be re-taken by German Crusaders in 1197. It remained a key Crusader stronghold until the Saracen invasion of 1249 when it was destroyed - this series of exchanges presented the backdrop for the ill-fated 7th Crusade.

The 7th Crusade was led by Louis IX of France from 1248 to 1254. Jerusalem had recently fallen and there was no popular enthusiasm at the time for a new crsusade, as Europe was involved in many internal conflicts. Bela IV of Hungary was rebuilding his kingdom from ashes after the devastating Mongol invasion of Europe. Henry III of England was struggling at home and Haakon IV of Norway was in the midst of a civil war. Louis IX was almost alone in declaring a new crusade to the east and in 1248 sailed from Aigues-Mortes and Marseilles with an army of 15,000. They sailed for Cyprus but Louis decided to focus first on attacking Egypt. While marching towards Cairo, Louis' main force was attacked by Mameluk Baibars and defeated. In 1250 while attempting to return to a safer location, Louis himself was captured and taken prisoner after his army was annihilated. He was ransomed for 800,000 bezants after which he fled to Acre, one of the safest crusader strongholds in Outremer. The French King re-enforced local defenses and moved north to Sidon.
