question:
The First British Empire was based on mercantilism, and involved colonies and holdings primarily in North America, the Caribbean, and India. Its growth was reversed by the loss of the American colonies in 1776. Britain made compensating gains in India, Australia, and in constructing an informal economic empire through control of trade and finance in Latin America after the independence of Spanish and Portuguese colonies about 1820. By the 1840s, Britain had adopted a highly successful policy of free trade that gave it dominance in the trade of much of the world. After losing its first Empire to the Americans, Britain then turned its attention towards Asia, Africa, and the Pacific. Following the defeat of Napoleonic France in 1815, Britain enjoyed a century of almost unchallenged dominance and expanded its imperial holdings around the globe. Increasing degrees of internal autonomy were granted to its white settler colonies in the 20th century.
answer:
What was the first British empire based on?


question:
After 1870, the new railroads across the Plains brought hunters who killed off almost all the bison for their hides. The railroads offered attractive packages of land and transportation to European farmers, who rushed to settle the land. They (and Americans as well) also took advantage of the homestead laws to obtain free farms. Land speculators and local boosters identified many potential towns, and those reached by the railroad had a chance, while the others became ghost towns. In Kansas, for example, nearly 5000 towns were mapped out, but by 1970 only 617 were actually operating. In the mid-20th century, closeness to an interstate exchange determined whether a town would flourish or struggle for business.
answer:
after about what year did railroads bring hunters to the great plains?
