The Battle for Caltharus, often spoken with the year 1515, was an invasion conducted by Lambertus III of Morstaybishlia from the 12th of January 1515 to the later stages of August that year for control over the Caltharusian throne. The conflict lasted through many strategically implemented episodes during 1515, however there was fighting before and after this period between the belligerents. The battle was delayed for several years and was triggered during 1515 after the government in control of Caltharus executed the remaining royal bloodline, angering both Lambertus III who was distantly related, and Katarina Leijonhufvud who was a direct descendant to the throne.

With the death of the last 6 heirs to the throne, besides Katarina, Lambertus amassed an army of just short of 21,000 soldiers that stormed the major cities until Lamburtupol, where the government in control held their ground for 46 days until the 29th of August when they fell.

The final victory concluded the end of the battle. The monarchy was re-established and Lambertus III was crowned High-King of the Morstaybishlian Empire on the 29th August. The remaining cousins of the monarchy, who had fled to Ethalria and Kostuvastan returned from exile. A feast on the 11th October began in Lambertupol to mark the victories. This day is celebrated annually around the world as Lambertus Day.

Lambertus did not return back to Bursil until 1517, establishing order and peace in Caltharus. He faced some challenges from Kostuvastan and Ethalria, both looking to expand their borders. He defended the border for a year and a half until a mutual agreement was held.

Rioting and anarchy continued for two decades, too small in size for the monarchy to consider dangerous. The rioting died down after time.

Because of Lambertus III's large success, he was given the epithet "the Great".
