General obligation bonds are a type of municipal government bond, which is government debt issued to raise money to finance public improvements. A general obligation bond is a municipal bond backed by the credit and taxing power of the issuing jurisdiction, rather than the revenue from a given project.
The Mexican-American War began because of a clash between the Mexican Army and the US Army in the disputed border area called the Neuces Strip (See the Thornton Affair-see Related Link shown below).
Why did, in 1846, did America declare war on Mexico. The war with Mexico was known as 'Mr Polk's war'. President Polk declared war on Mexico - or rather the US Congress did - because he wanted to gain lands from Mexico. Exactly which lands became clearer only as the war progressed. The specific dispute which sparked war in May 1846 was the 100-150 mile strip between two rivers, the Nueces and the Rio Grande.
