Spot Resolutions in the U.S. House of Representatives
December 22, 1847
In December 1847, Illinois Congressman Abraham Lincoln (1809–1865) introduced a series of resolutions in the House of Representatives that directly challenged President James K. Polk’s (1795–1849) justification for the Mexican-American War. Lincoln demanded that the president identify the exact geographic “spot” where American blood had allegedly been shed by Mexican forces and demonstrate that the incident occurred on undisputed United States territory. These resolutions emerged from Whig skepticism regarding the administration’s claims about the origins of the conflict and reflected broader concerns that executive action had preceded and shaped congressional authorization of war. Lincoln’s intervention centered constitutional and evidentiary scrutiny in the debate over the war’s legitimacy. His resolutions questioned the factual basis of Polk’s narrative and the reliability of presidential reports presented to Congress. In doing so, Lincoln emphasized the responsibility of the legislative branch to independently evaluate claims used to justify armed conflict. His position aligned with a faction of Whig opposition that viewed the war as an expansionist project tied to the extension of slavery into newly acquired territories. Although the Spot Resolutions did not halt the war effort, they became politically significant as an early example of Lincoln’s willingness to confront executive authority on constitutional grounds. Democratic critics portrayed the resolutions as unpatriotic and obstructive to military unity, contributing to Lincoln’s declining standing in the House. The episode highlights the emerging sectional and ideological divisions that would continue to shape American politics in the following decade.

WHEREAS the President of the United States, in his message of May 11th. 1846, has declared that “The Mexican Government not only refused to receive him, [the envoy of the U.S.] or listen to his propositions, but, after a long continued series of menaces, HAS at last invaded our teritory and shed the blood of our fellow-citizens on our own soil:

And again, in his message of December 8, 1846 that “We had ample cause of war against Mexico, long before the breaking out of hostilities. But even then we forbore to take redress into our own hands, until Mexico herself became the aggressor by invading our soil in hostile array, and shedding the blood of our citizens:”

And yet again, in his message of December 7, 1847, that “the Mexican Government refused even to hear the terms of adjustment which he [our minister of peace] was authorized to propose; and finally, under wholly unjustifiable pretexts, involved the two countries in war, by invading the territory of the State of Texas, striking the first blow, and shedding the blood of our citizens on our own soil

And whereas this House is desirous to obtain a full knowledge of all the facts which go to establish whether the particular spot of soil on which the blood of our citizens was so shed was or was not our own soil, at that time; Therefore,

Resolved by the House of Representatives, That the President of the United States be respectfully requested to inform this House—

1st. Whether the spot of soil on which the blood of our citizens was shed, as in his message declared, was or was not within the territory of Spain, at least from the treaty of 1819, until the Mexican revolution.

2d. Whether that spot is or is not within the territory which was wrested from Spain by the revolutionary Government of Mexico.

3d. Whether that spot is or is not within a settlement of people, which settlement had existed ever since long before the Texas revolution, and until its inhabitants fled before the approach of the United States Army.

4th. Whether that settlement is or is not isolated from any and all other settlements by the Gulf and the Rio Grande on the south and west, and by wide uninhabited regions on the north and east.

5th. Whether the people of that settlement, or a majority of them, or any of them, have ever submitted themselves to the government or laws of Texas or of the United States, by consent or by compulsion, either by accepting office, or voting at elections, or paying tax, or serving on juries, or having process served upon them, or in any other way.

6th. Whether the People of that settlement did or did not flee from the approach of the United States Army, leaving unprotected their homes and their growing crops, before the blood was shed, as in the messages stated; and whether the first blood, so shed, was or was not shed within the enclosure of one of the people who had thus fled from it.

7th. Whether our citizens, whose blood was shed, as in his messages declared, were or were not at that time, armed officers, and soldiers, sent into that settlement by the military order of the President through the Secretary of War.

8th. Whether the military force of the United States was or was not so sent into that settlement after Genl. Taylor had more than once intimated to the War Department that, in his opinion, no such movement was necessary to the defence or protection of Texas.
