The Kingdoms subtheme was introduced in 2010 and ran until 2012. Kingdoms takes place in a medieval time period with sets in a European style from the 15th century and is based off of two human kingdoms fighting each other, the Lion Kingdom and the Dragon Kingdom.
2011 LEGO Sets
In 2011, LEGO collectors saw major milestones, particularly with the release of the first-ever internal LEGO sets, Moulding Machines (4000001) and LOM 2011 Moulding (4000002). These exclusive sets, produced in limited quantities, set the foundation for highly valuable future collector items, making them some of the most sought-after LEGO releases among hardcore collectors.
