Problem: Influenced by papal bulls, Swedish magnates in the 12th century set up crusading expeditions to convert the heathens in the eastern Baltic. This resulted in the establishment of the Catholic Church, the Christian religion and the Swedish conquest of southern Finland in 1249. Turku, or Åbo, became the principal city in Finland and residence of a Bishopric. As a result of Protestant Reformation in the 16th century the Catholic Church had to give way for the Lutheran state church which was established by King Gustav Vasa of Sweden, whose principal reformer in Finland was Mikael Agricola and from 1554 also the Bishop. After the Finnish War in 1809, Finland became a part of the Russian Empire as an autonomous grand duchy. In 1817 the Bishop was created Archbishop and became head of the Church in Finland, which thereupon became the state church of the grand duchy. In 1870, the church was detached from the state as a separate judicial entity. After Finland had gained independence in 1917, through the constitution of 1919 and the act on religious freedom of 1922 the Evangelical Lutheran Church of Finland became a national church of Finland .

Problem: On 2 October 1187 the Ayyubid sultan Saladin captured Jerusalem and large parts of the Crusader states. In an effort to reclaim the Outremer estates, the Third Crusade was launched by King Philip II of France, King Richard I of England, and Emperor Frederick I of the Holy Roman Empire in 1189. Frederick departed with a huge army, defeated a Seljuk contingent near Philomelion and captured Iconium, but then drowned in the Göksu River near Silifke in Cilicia. Upon his death, Frederick's German crusading host, totaling perhaps 12,000 to 15,000 men, mostly disbanded and a much smaller contingent led by Frederick's son Duke Frederick V of Swabia continued to the Holy Land, where they joined the Siege of Acre. The crusade ended in the 1192 Treaty of Ramla signed by Sultan Saladin and King Richard Coeur de Lion, establishing a three-years armistice and allowing the Muslims to retain control over Jerusalem, while the Crusaders maintained Acre, Jaffa, and other key coastal cities.

Problem: There is a maximum limit on the total yearly employee pre-tax or Roth salary deferral into the plan. This limit, known as the "402(g) limit", was $15,500 for the year 2008; $16,500 for 2009-2011; $17,000 for 2012; $17,500 for 2013-2014; $18,000 for 2015-2017; and $18,500 for 2018. For future years, the limit may be indexed for inflation, increasing in increments of $500. Employees who are at least 50 years old at any time during the year are now allowed additional pre-tax "catch up" contributions of up to $5,000 for 2008; $5,500 for 2009-2014; and $6,000 for 2015-2018. The limit for future "catch up" contributions may also be adjusted for inflation in increments of $500. In eligible plans, employees can elect to contribute on a pre-tax basis or as a Roth 401(k) contribution, or a combination of the two, but the total of those two contributions amounts must not exceed the contribution limit in a single calendar year.  This limit does not apply to post-tax non-Roth elections.
