"The city of Budapest have been officially created on 17 November 1873 by the merger of the neighboring cities of Pest, Buda and Óbuda, with smaller outskirt towns amalgamated into the Greater Budapest in 1950. Its origins can be traced at Celtic people who have occupied the plains of Hungary from the 4th century BC, until its conquest by the Roman Empire who established the fortress and town of Aquincum on the site of today's Budapest around AD 100, and the subsequent arrival of the Hungarian people. Their conquest of the Carpathian Basin started at the end of the 9th century and the Kingdom of Hungary established on the year 1000. This book educates the reader about the history of Budapest from Prehistory to Present."
