It was called the Great Turkish War,  which started in 1683, with a huge invasion force of 140,000 men marching on Vienna. 
To stop the invasion, a Holy League was formed, made up by Austria, Poland , Venetians and the Russian Empire. They reconquered Hungary . At the same time, the Venetians launched an expedition into Greece, which conquered the Peloponnese. During the 1687 Venetian attacked on the city of Athens (conquered by the Ottomans), the Ottomans turned the ancient Parthenon into an ammunitions storehouse. A Venetian mortar hit the Parthenon, detonating the  gunpowder stored inside and partially destroying it.
The war ended with the Treaty of Karlowitz in 1699. 
 
        
             
        
        
        
Answer: RAILROADS
Explanation:
RAILROADS
Starting in the late 1820s, steam locomotives began to compete with horse-drawn locomotives. The railroads with steam locomotives offered a new mode of transportation that fascinated citizens, buoying their optimistic view of the possibilities of technological progress. The Mohawk and Hudson Railroad was the first to begin service with a steam locomotive. Its inaugural train ran in 1831 on a track outside Albany and covered twelve miles in twenty-five minutes. Soon it was traveling regularly between Albany and Schenectady.
Toward the middle of the century, railroad construction kicked into high gear, and eager investors quickly formed a number of railroad companies. As a railroad grid began to take shape, it stimulated a greater demand for coal, iron, and steel. Soon, both railroads and canals crisscrossed the states, providing a transportation infrastructure that fueled the growth of American commerce. Indeed, the transportation revolution led to development in the coal, iron, and steel industries, providing many Americans with new job opportunities.
 
        
                    
             
        
        
        
This is an example of "deductive reasoning".
Deductive reasoning is a legitimate procedure in which a conclusion depends on the concordance of various premises that are for the most part thought to be valid. Deductive thinking is some of the time alluded to as best down rationale. Its partner, inductive thinking, is some of the time alluded to as base up rationale.
