Problem: When King Frederick II was crowned in 1559, he immediately began expanding the navy. The number of bases, yards and vessels rose rapidly and substantial resources were used for new ship designs, weaponry, training and battle tactics. Sweden, which had become an independent country, dominated a large part of the Baltic Sea and threatened Danish merchant interests. In retaliation, Denmark closed the resund in 1568, laying the first seeds for the Scanian War , only eight years after the end of the second Nordic War , during which Denmark lost the now Swedish provinces of Skane, Halland and Blekinge. During this period, further resources were allocated to the navy. Cort Adeler and Niels Juel led the Danish navy to a victory in the Battle of Kge Bay in 1677. King Christian IV continued in his father's footsteps. In the beginning of the 17th century, he considerably expanded the naval workships. In Copenhagen, where the navy resided, he built a large number of homes for crewmembers and workshop craftsmen the most famous being Nyboder which still stands in central Copenhagen. General admiral lieutenant Ulrik Christian Gyldenlve was appointed supreme commander of the navy in 1701. He raised the status of the naval profession and established Skadetakademie, the predecessor of the Royal Danish Naval Academy. In 1709, Peter Jansen Wessel joined the navy. He was later given the rank of admiral as a reward for his many victories - most famously at Marstrand and Dynekilden. He was later known as Tordenskjold.

Problem: Speed skating After a successful period around 1900, with Jaap Eden and Coen de Koning as World Champions, Dutch speed skating successes became numerous in the 1960s. Champions Kees Verkerk and Ard Schenk were immensely popular, causing a real speed skating hype in the country. Successes continue up to today, with the likes of Yvonne van Gennip (3 Olympic gold medals in 1988), Rintje Ritsma (4-time World Allround Champion), Jochem Uytdehaage (2 Olympic gold medals in 2002), Marianne Timmer (3 Olympic gold medals in 1998 and 2006), Ireen Wust (5 Olympic golds in 2006, 2010, 2014, 2018 and 6 World Allround Speed Skating Championships) and Sven Kramer (4 Olympic gold medals in 2010, 2014, 2018 and 9 World Allround Championships). The Dutch speed skaters performance at the 2014 Winter Olympics, where they won 8 out of 12 events, 23 out of 36 medals, including 4 clean sweeps, is the most dominant performance in a single sport in Olympic history. Thialf Stadium in Heerenveen was the second indoor 400m speed skating oval in the world, the first to host an international championship and remains a world-class facility today. Dutch speed skaters have won 77 world single distance championchips (since 1996).
