The high point of achievement in Mughal architecture
(Indo-Islamic architecture developed by Mughals in 16th century), represents
the Taj Mahal, described as the “teardrop on the cheek of time” by Rabindranath
Tagore. Emperor Shah Jahan built the Taj Mahal entirely of white marble in
memory of his wife Mumtay Mahal. Shah Jahan decorated the building with large
scale-inlaid work of jewels and symmetrical mirror mosque in red sandstone. The
construction took over 22 years and required 22,000 workers and 1,000
elephants, at cost of approximately 32 million rupees. The Taj Mahal now
represents one of the New Seven Wonder of the World.
So the Great War (World War One) was a war that started in 1914 and finish on November 11, 1918. It lasted for four years.
Now the start of the war:
began in 1914 after the assassination of Archduke Franz Ferdinand of Austria. His murder catapulted into a war across Europe
The U.S. didn't go into war for about 2 and an a half years, During the conflict, Germany, Austria-Hungary, Bulgaria and the Ottoman Empire (the Central Powers) fought against Great Britain, France, Russia, Italy, Romania, Japan and the United States (the Allied Powers).
By the time the war was over and the Allied Powers claimed victory, more than 16 million people—soldiers and civilians alike—were dead.
The abbreviation for before the birth of Christ is B.C.
It stands for "before Christ".
