Alma Ch51

More corruption among the Nephites with a group named the king-men, who are trying to change laws in order to set up a king. The other political party is the freemen who are supported by the voice of the people and Moroni who, as the military leader, forces the king-men to choose to be peaceful or die. Hard choice right? But through all this political upheaval, there is less focus on the Lamanites who attack and capture some cities. Then the cool story that Teancum is really famous for is told, but not spoilers, you're just going to have to read the whole thing!
So it is starting the 25th year in peace but soon there were people who were wanting the law to change, so they petitioned but Pahoran refused their desires and that made some of them pretty heated wanting to overthrow the government in favor of being ruled by a king again (v1-5). Two political parties arouse and brought their despute to a vote; the people who wanted things to stay the same were called freemen and had sworn to protect their liberty while the people who wanted a king again called king-men and they were power hungry (v6-8). The people voted, and it was settled that the law will not change, but this happened just as the Lamanites were coming upon them to attack again with as many people as Amalickiah could bring to attack the city of Zarahemla just as the voting had finished (v9-12).
When the king-men saw the Lamanites coming they refused to fight for freedom, but Moroni gained power, through petition, as the captain of the army to compel any dissenters to fight for the cause of freedom or be put to death (v13-15). While trying to prevent contentions among the Nephites, Moroni had to fight the king-men to pull down their pride and their nobility and ended up killing 4,000 dissenters and imprisoning several of the leader before the rest would join in defending their country from the real enemy (v16-20). This was an end to king-men in Zarahemla because they were humbled by Moroni who knew it was necessary to stop the contentions among the Nephites (v21-22).
The Lamanites made a lot of progress while Moroni was busy and took over 7 cities even though they had been fortified which means now the Lamanites possess strongholds that are fortified (v23-27). They then marched to Bountiful and was finally met with the army that is led by Teancum, who had an army that bested the Lamanites from superior strength (v28-31). After a long day of battle, the armies were settled for sleep to be ready to fight the next day (v32).
Ready for Teancum's famous story!?! Ok so as everyone is sleeping, Teancum and a servant sneak right into the camp of Amalickiah and weren't even noticed because of their much fatigue (v33). Teancum quitely sneaks into Amalickiah's tent and kills him in sleep so quickly that no one was disturbed in their sleep (v34). The two return back to their own camp and ready the army to prepare for whatever reaction the Lamanites will have to their king being slain on the last day of the year 25 (v35-37).
