<span>a. Southern congressmen opposed the banning of slavery from the new territories
</span><span>Northern states and southern states were at odds over the potential spread of slavery in new states and what that would do to the balance of power in Congress. <span>
In 1846, Congressman David Wilmot of Pennsylvania introduced the proviso as an amendment to an appropriations bill in connection with the peace treaty being negotiated with Mexico. His amendment stipulated that any territory gained from Mexico would be free, not allowing slavery. Wilmot's amendment passed in the House of Representatives, but was unable to get approval in the Senate. The Compromise of 1850, a package of five bills passed by Congress in September of that year, sought to accommodate some of the issues both South and North were debating over during those years. But we know that war over the slavery issue was yet to come.</span></span>
The answer is Tariff of 1816.
Hope that helps!
<span>The Sudetenland contained 3.5 million Germans who had been cut off from the rest of Germany after the creation of Czechoslovakia by the Treaty of Versailles. Hitler felt he had a legitimate claim upon the area because he saw it as German land. Also, Sudeten Germans claimed they were victimized by the Czech government and wanted home rule or union with Germany. Britain was reluctant to involve herself because she had inadequate armed forces to do so and had no treaty obligations to Czechoslovakia. After the Bad Godesberg and Munich conferences the four main European powers (Britain, France, Italy and Germany) decided, without the presence of the Czech leader, to give the Sudetenland to Hitler over a ten day period. The Czechs had little alternative but to agree to Hitler's demands, as they had few allies and a weak army. (However they did have an alliance with France which they failed to honor) By the 1st of October 1938 the Sudetenland had been fully surrendered to Hitler.</span>
