Ladislaus I of Hungary
In 1784, Juraj Sklenár, a Slovak historian and teacher of rhetoric in Pressburg (today's Bratislava), published "Vetustissumus magnae Moravie situs et primus in eam Hungarorum ingressus et incursus" (). His work had a political purpose and character. He argued that the Magyars never conquered the territory inhabited by the Slovaks and the latter voluntarily joined the Kingdom of Hungary during the rule of Ladislaus I of Hungary.
