Answer:
1) The spread of Islam spans about 1,400 years. Muslim conquests following Muhammad's death led to the creation of the caliphates, occupying a vast geographical area; conversion to Islam was boosted by Arab Muslim forces conquering vast territories and building imperial structures over time. Most of the significant expansion occurred during the reign of the Rashidun from 632 to 661 CE, which was the reign of the first four successors of Muhammad. These early caliphates, coupled with Muslim economics and trading, the Islamic Golden Age, and the age of the Islamic gunpowder empires, resulted in Islam's spread outwards from Mecca towards the Indian, Atlantic, and Pacific Oceans and the creation of the Muslim world. Trade played an important role in the spread of Islam in several parts of the world, especially Indian traders in Southeast Asia.[
2)Trade has played a major role in U.S. history. The Founders cited Britain’s “cutting off our Trade with all parts of the world” as a reason for declaring independence. The Framers of the U.S. Constitution created a free trade area among the states that allowed interstate commerce to flow freely. The process of economic specialization and trade, in which individuals focus on doing the things they do best and then exchange the products of their labor with others who are likewise concentrating on their own areas of excellence, leads to much higher levels of production of goods and services as well as the most efficient use of labor and resources. It is this process that creates and sustains the markets of the “free market” system. The development of this system upended feudalism and brought about dramatic and revolutionary improvements in living standards that characterize the modern age. Free and open trade has fueled vibrant competition, innovation, and economies of scale, allowing individuals and businesses to take advantage of lower prices and increased choice. As a result, billions of people around the world have escaped the constraints of subsistence farming and extreme poverty that characterized the lives of most of humanity throughout history.
