Kuruc Invasions: From the 15th century onwards Hungarian revolutionaries called themselves "Kuruc" (meaning "carrier of a cross"). In a rising against the Habsburgs under Ferenc II Rákóczi Kuruc rebels attacked and devastated parts of Lower Austria, Burgenland and Styria several times between 1703 and 1709. In order to protect Vienna a rampart was built in 1704 (along the present-day Guertel road) and several earthworks were erected from Lake Neusiedl to the River Danube.
