Some 1,500 guests of honor attended the parade, among them Czech President Milos Zeman and US Secretary of Defense James Mattis.
Over 4,000 soldiers took part in the military parade, the largest since the end of the Cold War in Prague, marking the founding of Czechoslovakia in October 1918.
Troops from NATO allies Britain, France, Italy and the US also joined the parade.
In a brief address, President Milos Zeman highlighted the role of the Czech army and security forces in the fight against international terror, something he described as humanity’s greatest enemy.
Besides, many celebrations will also mark that important date, including gatherings, exhibitions, concerts and shows.
The independent state was peacefully split into the Czech Republic and Slovakia in 1993.
The Czech Republic joined NATO in 1999 and the EU in 2004./.
