In the other direction, European Christian armies conquered Palestine for a time during the Crusades 11th-13th centuries, founding three Christian kingdoms and settling them with Christian Knights and their families. This permanent migration was relatively small however and was one of the reasons why the Crusaders eventually lost the their hold on the Holy Lands.
The medieval period, although often presented as a time of limited human mobility and slow social change in the history of Europe, in fact saw widespread movement of peoples. The Vikings from Scandinavia raided all over Europe from the 8th century and settled in many places, including Normandy, the north of England, Scotland and Ireland (most of whose urban centres were founded by the Vikings). The Normans later conquered the Saxon Kingdom of (Northumbria) England, most of Ireland, southern Italy and Sicily -although the migration associated with these conquests was relatively limited - the Normans in most cases forming only a small ruling class. Iberia was invaded by Muslim Arabs, Berbers and Moors in , founding new Kingdoms such as al Andalus and bringing with them a wave of settlers from North Africa.
The Magna Carta was originally written in Latin. A large part of Magna Carta was copied, nearly word for word, from the Charter of Liberties of Henry I, issued when Henry I ascended to the throne in 1100, which bound the king to certain laws regarding the treatment of church officials and nobles, effectively granting certain civil liberties to the church and the English nobility. The Charter was reissued three times in the reign of Henry III (1216, 1217 and 1225) in order to provide for an updated version. After this each individual king for the next two-hundred years (until Henry V in 1416) personally confirmed the 1225 charter in their own charter. The Great Council only existed to give input on the opinion of the kingdom as a whole, and only had power in relation to scutage until 1258 when Henry III got into debt fighting in Sicily for the pope. The Barons agreed to a tax in return for reform, leading to the Provisions of Oxford. But Henry got a papal bull allowing him to set aside the provisions and in 1262 told royal officers to ignore the provisions and only to obey Magna Carta. The Barons revolted and seized the Tower of London, the cinque ports and Gloucester. Initially the king surrendered, but when Louis IX (of France) arbitrated in favor of Henry, Henry crushed the rebellion. Later he ceded somewhat, passing the Statute of Marlborough in 1267 that allowed writs for breaches of Magna Carta to be free of charge, enabling anyone to have standing to apply the charter. This secured the position of the council forever but its powers were still very limited. The council originally only met three times a year, when the king wore his crown, and so was subservient to the king’s council, Curiae Regis, who, unlike the Great Council, followed the king wherever he went unlike the Great Council.
Magna Carta had little effect on the rest of the development of parliament until the Tudor period. Knights and county representatives attended the Great Council (Simon de Montfort’s Parliament), and the council became far more representative under the model parliament of Edward I which included two knights from each county, two burgesses from each borough and two citizens from each city. The commons separated from the Lords in 1341. The right of commons to exclusively sanction taxes (based on a withdrawn provision of Magna Carta) was re-asserted in 1407, although it was not in force in this period. The power vested in the Great Council by, albeit withdrawn, Clause 14 of Magna Carta became vested in the House of Commons but Magna Carta was all but forgotten for about a century, until the Tudors.
The first uses of the charter as a bill of rights was used widely in the reign of Henry VIII, but it seems that it was seen as any other statute which could be amended and removed. But later in the reign, the Lord Treasurer stated in the Star Chamber that many had lost their lives in the Baronial wars fighting for the liberties, which were guaranteed by The Charter, and therefore it should not so easily be overlooked as a simple and regular statute. Although the early Tudor period saw a re-awaking of the use of Magna Carta in the common law, it was not seen, as it was later, as an entrenched set of liberties guaranteed for the people against The Crown and Government. Therefore The Charter had little effect on the governance of the early Tudor period. The Charter had no real effect until the Elizabethan age. It was an age of expansion and exploration abroad, while at home the Protestant Reformation became entrenched in the national mindset.
France was embroiled in its own religious battles that would only be settled in 1598 with the Edict of Nantes. Thus attempts were made to prove that Parliament had Roman origins. The Charter was rightfully interpreted as an attempt to return to a pre-Norman state of things. The Charter was seen as important as a statement as to the pre-Norman antiquity of Parliament. Cromwell himself had much disdain for the Magna Carta. The Levellers claimed Magna Carta was above any branch of government, and this led to the upper echelons of the Leveller movement denouncing Parliament. The Diggers were a very early socialistic group who called for all land to be available to all for farming and the like.
