"Sovereignty" means control over one's own nation or territory.
Hawaii was concerned with sovereignty in 1884 because in that year the Kingdom of Hawaii was signing a treaty that gave the United States "the exclusive right to enter the harbor of the Pearl River in the Island of Oahu" (in other words, Pearl Harbor), "and to establish and maintain there a coaling and repair station for the use of vessels of the United States, and to that end the United States may improve the entrance to said harbor and do all other things needful to the purpose aforesaid." (You can tell I'm quoting from the actual treaty there.)
When the treaty was reaffirmed and extended in 1887, King Kalaukaua of Hawaii said to the Hawaiian legislature that his government had assurances from the US government that the treaty did "not cede any territory or part with or impair any right of sovereignty or jurisdiction on the part of the Hawaiian Kingdom."
Ultimately, however, in an age when imperialism was common throughout the world, the United States did take over control of Hawaii. In the late 1800s, the US supported American sugar planters who overthrew the Hawaiian monarchy, and by 1900 Hawaii became a US territory.
Answer:
He is also known for his discovery of the photoelectric effect, for which he won the Nobel Prize for Physics in 1921. Einstein developed a theory of special and general relativity, which helped to complicate and expand upon theories that had been put forth by Isaac Newton over 200 years prior.
Explanation:
Industrialization quickly changed the landscape of the United States and other countries in the 19th century. Construction materials, like steel and iron were needed for buildings, factories, and railroads. Oil was discovered to be a great source of fuel. The Spindletop Geyser in Beaumont, Texas was discovered in 1901, and over 1000 oil companies were chartered. 8 years later, the U.S.'s oil production was more than the rest of the world's oil production combined.
The correct answer is agreeing not to end the slave trade for at least 20 years.
In order to compromise on the issue, individuals from the north and south had to find a middle ground in terms of the slave trade. This is why the slave trade would be banned as of 1808. When they made this agreement in 1788, this satisfied both parties as the northerners wanted to stop this inhumane exchange of people while southerners the chance to gain more labor for their plantations.
