Whose message to congress stated that mexico had passed the boundary of the united states, has invaded our territory and shed american blood on american soil.

The right answer is James K Polk (President of America), whose message to the congress stated that Mexico had passed the boundary of the United States, has invaded our territory and shed American blood on American soil.

James K Polk was elected the U.S President on a platform of expansionism who supervised the highest territorial extension of the United States. In 1846, he directed the commander of the army in Texas to lead his troops in the disputed lands between the two rivers Rio Grande and Nueces. A few months later, He sent a mission under the leadership of John Slidell ( a congressman) to Mexico to buy the disputed territory along the Texas- Mexican frontier. Following the failure of the mission Polk in 1846, He managed to use the news of the encounter inside the disputed area between the forces of Taylor and Mexican's, to achieve the support of Congress for its declaration of war against Mexico.

by 1890, the united states had by far the world's most productive economy. american industry produced twice as much as its closest competitor--britain. but the united states was not a great military or diplomatic power. its army numbered less than 30,000 troops, and its navy had only about 10,000 seamen. britain's army was five times the size of its american counterpart, and its navy was ten times bigger. the united states' military was small because the country was situated between two large oceans and was surrounded by weak or friendly nations. it faced no serious military threats and had little interest in asserting military power overseas.

the correct answer is "pioneers carried all of their possessions on long and dangerous trails".

the first wave of pioneers travelled in 1842. they were merely 100 people. the next year that sum climbed to 1000 men, women, and children. these people travelled around 2,000 miles to oregon in the hopes of a better life. although the first part of the trip didn't present many obstacles, as time and miles went by they learnt that threat came from simple things, like becoming ill due to unclean water or bad food.

the weather didn't much, as wagons couldn't protect them from storms. as they travelled through the desert, the intense heat caused wood to shrink. their own lips abscessed and split because of the dry air. the only cure for this was to rub axle grease on their lips.

even crossing rivers was dangerous. sometimes wheels were damaged by unseen rocks on shallow water. mud didn't much either. pioneers were afraid of indian attacks, but there aren't many records of fights between pioneers and native americans. accidents happened because of negligence, exhaustion, guns, and bad weather.

history says that 1 of 10 pioneers who travelled to oregon didn't survive the journey. diseases spread fastly because they didn't have doctors and medical care was ofently improvised. one of the most deadly diseases they came upon was cholera, which became a worldwide pandemia.
