The two highlighted text examples that provide reasons for Alabama's secession are:
-
The election of Abraham Lincoln and Hannibal Hamlin to the offices of president and vice-president of the United States of America, by a sectional party, avowedly hostile to the domestic institutions and to the peace and security of the people of the State of Alabama.
-
Many and dangerous infractions of the constitution of the United States by many of the States and people of the Northern section.
These statements emphasize Alabama's perception of a threat to its domestic institutions and constitutional rights, which they argue justifies their withdrawal from the Union.
