Mateus I, nicknamed The Tyrant, (Rio de Janeiro, Brazil, 15 September 1999) was the second King of Ebenthal. Born in Rio de Janeiro, upon his brother King Arthur I's ascension to the throne of Ebenthal in August 2014, Mateus became his brother's presumptive heir under the title of Prince of Arturia, during which time he performed minor roles such as representing his brother on his absence and advise him. In 24 June 2019, when Arthur I abdicated the Ebenthali throne, he was succeeded by Mateus. His brief rign was chaotic. Soon after assuming the throne Mateus acted as an autocrat, issued unconstitutional decreed and openly planned to completely restructure Ebenthal's political hierarchy, ignoring the parliament and justice, which sparked the series of events collectively called Mateusian Crisis. After he tried to seize absolute power by abusing his powers and firing the members of the the country's political center, supported by a clique of nobles and military and in conflict with the country's institutions and most of its political class and resident population, the Tribune of Truth, the Conclave of Ebenthal and the Royal Ebenthali Army, respectively headed by Pedro Reis, 1st Count of Gesetzhausen, Nícollas Reis, 1st Duke of Novaes and Raphael Sousa, 1st Duke of Sternachten, overthrew him in 27 September 2019 in order to prevent Ebenthal from dissolve, thus ending the reign of the House of Beato and creating the 2019 Ebenthaler interregnum. Mateus was later judged and declared an enemy of Ebenthal and sentenced to death by drowning in acid, commuted to perpetual exile. After his deposition a regency was created and he was finally succeeded by Arthur II as King of Ebenthal in 29 December 2019.
