Known enterprise "Praga" as its brand name and coat of arms took the capital of Czechoslovakia. At the beginning of the XX century it became the basis of two large Prague company - "First Czech-Moravian Machine-Building Plant" and the company Franz Ringhoffer , Xia found necessary then the Austro-Hungarian Empire. March 27, 1907 they signed an agreement on the organization of "Prague Automobile Plant" (Prazska tovarna na automobily), for which poaroili shop in Prague-Liben quarter, and in the same year from imported parts have started to assemble cars of the brand "Praga".

Later, power increased to 35 hp, and load capacity - up to 3 tons. Its development was the 2-ton machine "R" with an engine capacity of 35 hp At the same time the plant produced a 5-ton truck 40-strong model "T", and in 1915 began manufacturing the machines known series "N", nicknamed "Enka" and are available up to 1937
In the 20-ies., Despite the crisis, the factory shop "Praga" expanded and installed new equipment, making it one of the largest in the country. At this time, in addition to the upgraded 50-strong model "N", issued 30-strong truck "L", sweeper "BD" and the popular 1-ton car "AN" on the car chassis "Alfa" a 1.2 -liter engine 18 hp (later - 30-40 hp).

These primarily include the family of truck chassis on the famous "N" with diesel engines (6,75-8,85 l 55-125 hp) manufactured under license from German firm "Deutz". Cars models "ND" and "SND" had capacity up to 7.5 tonnes, at what some were equipped with 7- and 8-speed. Buses "NDO" first got semi-automatic gearbox.

His version of "RND" received a 4-cylinder 4.5-liter diesel engine 52-60 hp These trucks are distinguished by high performance, high-speed and cost, well proven in the army. On the basis of their proposed dump trucks, utilities, health, fire and special machines installed bus body on 62 passengers. In the 3-ton version they released until 1953 Licenses are purchased Yugoslav factory THERE. On the basis of a series of "RN" in 1935 ~ 39 years. produced 3-axle army vehicle "RV" (6x4) 2 t lifting capacity, equipped with a 2-stage splitter in the transmission. He had independent front torsion bar suspension, the rear wheels were mounted on longitudinal semi springs and drives swinging half-axles. Maximum printing speed reached 70 km / h. At the same time produced a 4-ton version of "SV" and Utility "AV" (6x4). Since the beginning of the Second World War car production was limited, and in 1943 completely stopped.
The plant switched to perform German military orders, releasing semi-tracked tractors 5-ton class, engines and transmissions for the tanks.
