The reform movement in politics, the society, and the economy was known as the Progressive movement.
This movement took several different steps to change American society. This included
A) The development of anti-trust laws- This would clean up the economy and stop monopolies from cornering markets and participating in price gouging.
B) Muckraking- Journalists exposed social ills in American society by writing influential books and using photographs to show things like the horrible working and living conditons of American citizens. This lead to changes in law (like the Meat Inspection Act) that increased consumer and worker safety.
C) 17th amendment- This lead to citizens voting directly for their US Senators instead of having them picked by members of the state legislature. This helped to stop political corruption.
Rise
The rise of Islam in Africa and Asia was a consequences of years of military and political strategies as well as missionary work. After the Arab peninsula was united under one leadership of the prophet of Islam, there was enough stability and funding to expand abroad.
Islam grew out of a region that is correctly identified as the Middle East, completely in between both Africa and vast Asia.
The natural expansion of the religion took place in Palestine and to the east in, Syria and Persia up til modern-day Pakistan.
On the west, the expansion was naturally in Egypt and North Africa.
Fall
While Islam never 'Fell' out of Africa, there was a marked decline in Islamic Empires. This was mostly due to European powers who were scrambling for Africa. This saw the English, French, Belgians all conquer large parts of the land and use them for slaves and other trades.
The idea that a country or region should specialise in making and exporting goods and services that it can produce most efficiently.
Sorry but, Iraq was never involved in World War 1. Don’t know if you mean the Iran-Iraq war...but Iraq was never in WW1.
It remade Europe after the downfall of French Emperor Napoleon I and tried to restore old boundaries as well as resizing the main powers so they could balance each other and remain at peace.
