Here are some one liners...
The Tariff of Abomination -- The Congress produces a tariff so convoluted that is pleases enough people to vote for it, but no one loves it. It is going to cause real problems down the line.
The Beginning of the Liberal Wars -- It is the aristocrats against those who dream of liberty. (Liberty will win but not this year.)
The Red Barn Murder -- Bill and Maria elope but only one of them will make it to the honeymoon.
In Other News -- Jules Verne, the Red Cross and the DC motor.
The Tariff of AbominationThe economic line between the Northern states and Southern states is well drawn. As an industrial economy, the North fears cheap imports from Britain killing their emerging businesses. The agrarian economy of the South wants to sell raw materials to Britain in exchange for hard currency that seems to find its way North no matter what they do. President John Quincy Adams is from Massachusetts, so he wants a protective tariff to force citizens to "Buy American." (They don't say it that way, but that is what they are thinking.) The South hates any tariff with a hot, hot hate. Tariffs always add a significant burden to the Southern economy by increasing the price of manufactured goods. Then the Southern economy must wave bye-bye to their hard currency as it heads North into the pockets of the manufacturers. To cobble together the votes needed for passage, the tariff soon becomes an obvious political payoff to various constituencies. The Southern representatives call it the Tariff of Abomination. It passes and America's economy goes south. By 1832, it will reach a crises point. South Carolina will declare the Tariff of Abomination unconstitutional and nullify the law. At this point it is an open question whether a state has the authority to nullify a Federal law under this circumstance. When the question comes up, Andrew Jackson will be President. Jackson is a law-and-order guy, so the fur is going to fly.   
The Beginning of the Liberal WarsAlthough the Napoleonic wars of conquest are over, rebellion has broken out in Portugal. After the death of King John the 6th, the succession has come into dispute because King John's elder son, Pedro, is already ruling in Brazil. John's younger son, Miguel, points out that Brazil is now independent so Miguel should take the throne. Neither Portugal nor Brazil want reunification, so Pedro abdicates the throne of Portugal in favor of his 7-year-old daughter, Maria, rather than his brother. Maria needs a regent and regency politics are always tricky, so Pedro attempts to appease the various factions by emending Portugal's constitution to join the opposing factions and then names his sister as regent. That doesn't work out. The conservative aristocracy still want Miguel as ruler and want to rid themselves of the Napoleonic legal liberties imposed upon them. Miguel agrees, takes the throne and starts putting things right. ("Right" is defined as back to the good old days with the good old boys in charge.) Those who prefer the Napoleonic liberties are called Liberals and thus the Liberal Wars begin. Mass arrests. Blood and sorrow. The Liberals are going to win, but its going to take a while. 
The Red Barn MurderJust some friendly advice to all young lovers: if it doesn't work out, please don't murder each other, but if you must murder, don't bury the body in a big red barn where her stepmother will find the body. Supposedly, Bill and Maria are to elope that evening. Certainly Maria thinks so. Bill doesn't show, giving the excuse that his brother has taken ill. He shows up at Maria's house the next day and tells her that the sheriff has a warrant for her arrest. Bill says he will carry her things to the red barn about a half mile away and meet her there. Then they will sneak out of town together. Maria is never seen alive again. Her stepmother gets plenty of newsy letters from her new son-in-law, Bill. What a treat! But she wonders why Maria is not writing to her directly. After a prophetic dream, Maria's stepmother convinces her husband to take her to the red barn. They find Maria's body in one of the grain bins, tied in a sack with Bill's handkerchief still wrapped around her neck. It is easy enough to find Bill. He is now married to Mary and running a boarding house for ladies. Bill says that Maria's death was an accident. After the trial of the century, Bill swings. 20,000 people show up to share in the experience and the town will become a tourist attraction for years to come.
