Cars came into use all over the world in the 20th century, and developed economies depended on them. The year 1886 is considered the birth year of the modern automobile, when German inventor Karl Benz patented his Benz Patent Motor Car. In the early 20th century, cars became widely available. One of the first cars available to the masses was the 1908 Model T, an American car manufactured by the Ford Motor Company. Cars were quickly adopted in the U.S., where they replaced animal drawn carriages and carts, but it took much longer for them to be accepted in Western Europe and other parts of the world.
In November 1881, French inventor Gustave Trouvé demonstrated the first working (three-wheeled) car powered by electricity at the International Electricity Exhibition in Paris. Although several other German engineers (including Gottlieb Daimler, Wilhelm Maybach, and Siegfried Marcus) were working on the problem at about the same time, Karl Benz is generally recognized as the inventor of the modern automobile.
The original Benz Patent-Motorwagen, first built in 1885 and patented for concept in 1879, became the patent for his first engine, developed in 1878. Many of his other inventions made possible the use of the internal combustion engine to power a vehicle. His first motor car was built in Mannheim, Germany, in 1885. The patent for his invention was granted to him from his application on January 29, 1886 (under the auspices of his large company Benz & Cie. founded in 1883). Benz began promoting the vehicle on July 3, 1886, and about 25 Benz vehicles were sold between 1888 and 1893, when his first four-wheeled vehicle was introduced along with a cheaper model. They too were powered by Four-stroke engines of his own design. The Frenchman Emile Roger, who was already producing Benz engines under license, now included the Benz car in his product line. Since France was more receptive to the early cars, more were built by Roger in France initially built and sold more than Benz did in Germany. In August 1888, Bertha Benz, the wife of Karl Benz, took the first car ride to prove the roadworthiness of her husband's invention.
