The New-York Tribune announces a major redesign—new beautiful type across all editions—while its editor Horace Greeley lays out an ambitious manifesto for the paper's mission. The Tribune declares itself a journal of "Progress and Reform," devoted to the Whig cause and staunchly opposed to the Mexican-American War, which Greeley condemns as "an unrighteous War" motivated by slavery expansion. He urges immediate peace negotiations and the withdrawal of U.S. troops from Mexican territory, insisting "the conditions of Peace might be settled within a month." Simultaneously, the paper covers New York's Constitutional Convention in its seventh week, reporting on debates over voting rights (including whether Black men should vote and whether literacy should be required), the election of local officers, canal policy, and the definition of treason. One correspondent argues that only those who can read should be permitted to vote, citing 500,000 Americans over age 20 who cannot read—mostly in slave states.

July 1846 was a pivot point in American history. The Mexican-American War had begun just two months earlier, and the nation was already fracturing over whether newly conquered western territory would permit slavery. Greeley's Tribune, founded in 1841, was emerging as a powerful voice against the war—a position that would define his influence through the 1850s and into the Civil War era. Meanwhile, New York's constitutional convention was grappling with democracy itself: who gets to vote, how should power be distributed, what role should the state play in controlling commerce and industry? These weren't academic questions—they were the scaffolding upon which American democracy would either expand or contract.

• The Tribune charges $5 per year for daily subscriptions, $3 for semi-weekly, and $2 for weekly—but offers a bulk discount: 20 copies of the weekly for $24 (roughly $1.20 per paper). This suggests the paper was already targeting group subscriptions for reading circles and community organizations.
• The paper is selling off its old typeface: 1,300 lbs of Minion type and 500 lbs of Nonpareil type at 20-25 cents per pound for cash. This was major equipment—a full printing operation's worth—being liquidated to make room for the new type.
• A correspondent proposes that under-21-year-olds should NOT be admitted as voters, and scolds the editor of 'Young America' (a rival publication) for even suggesting it. This reveals fierce debate over the voting age in 1846—some progressives wanted to lower it.
• The New York Secretary of State reported that the 1845 legislature sat for 142 days straight (including Sundays). This exhausting schedule was already prompting calls for constitutional reform to limit session length.
• The paper offers to accept 'Bills of any specie-paying Bank in the Union' for subscriptions—a striking detail revealing how fragmented American currency was in 1846, before the Civil War standardized it.

• Horace Greeley's famous slogan 'Go West, young man' wouldn't be written for another decade, but this July 1846 manifesto shows him already positioning the Tribune as a voice for American expansion and opportunity—just not via conquest and slavery. The tension between westward ambition and anti-slavery conviction would define his career until his death in 1872.
• Greeley's call for peace with Mexico 'within a month' was radically optimistic. The war would drag on for another 20 months, costing 13,000 American lives, and would ultimately add 525,000 square miles to the United States—almost all of it destined for slavery expansion, proving Greeley's worst fears correct.
• The Tribune's three foreign correspondents stationed in Britain, France, and Eastern Europe in 1846 were cutting-edge: transatlantic telegraph cables wouldn't exist for another 11 years. News from Europe took weeks to arrive by ship, making these correspondents essential.
• The Constitutional Convention debating whether Black men should vote in 1846 New York was ahead of the nation—Black men wouldn't gain the federal vote until the 15th Amendment (1870), and New York itself wouldn't grant Black suffrage until 1870.
• The paper's opposition to 'Banks and other institutes of the existing order' reflects that Jacksonian anti-bank sentiment was still alive in 1846, even as Greeley himself would evolve into a defender of industrial capitalism by the 1850s.
