History: The Year is 1467

I've uploaded year 1467 to the TSP Wiki...

Here are some one liners...

The First Multi-Alphabetic Cypher -- I talk about a code disk invented this year that will have use all the way into the 20th century with the Enigma machine. I also mention George Washington's code book again.

The Great Brotherhood War -- Galacia in Spain is a lawless region so the peasants get together and fight the nobles who are causing the trouble. I also talk about civil war reenactments and muskets.

Inuyasha and the Warring States Period -- Japan begins the Warring States period that has references in modern culture today including video games, movies and the cartoon character, Inuyasha.

The First Multi-Alphabetic Cypher

Leon Battista Alberti is known as an architect and his books will be required reading well into the 18th century, but he is also a mathematician. He has developed the first cypher code based on multi-alphabetic substitution using a code disk. The code key changes every four words so that the enciphered text is resistant to frequency analysis. (That is... looking for the most frequently used letter such as 'e' won't help to break the code.) Of course, one must send the code disk to the people who receive your messages. This type of coding will continue into the 20th century and the Enigma machine that the Nazis used to encrypt their messages is an example of a rotating disc code. [1] [2] [3] [4] [5] [6]
My Take by Alex Shrugged
The problem with any system using a code disk is that once someone gains possession of the disk, your encrypted messages will be readable. George Washington and his Culper Ring of spies had a much easier method, writing down a page number and the position of a word on that page rather than writing the word itself. As long as you both had duplicate books, it worked. Possession of a book would not mark you as a spy the way possession of a code disk would.[7]

The Great Brotherhood War

Galacia is north of Portugal in modern day Spain. At the end of the Middle Ages the king has not extended his influence that far, so law and order, such as it is, has been left to the local nobles. They have been fighting amongst each other and plundering from each others lands so the people have risen up to put a stop to the chaos. A few knights have joined with the peasants to attack various castles in the region. They are using trebuchets and fire to bring down the castles and chase out the nobles. Eventually Queen Isabella will establish the rule of law in the region. Galacia won't like her interference, but she will chase out some of the worst of the nobles. [8] [9] [10]
My Take by Alex Shrugged
In the modern day, Galacia sponsors the world largest civil war reenactment. I assume the Brotherhood War reenactment is run similar to American civil war reenactments. A type of musket does exist during the time of the Brotherhood War. It is called an arquebus but it has been used mostly by the Black Army of Hungry, so it probably wasn't used in this war. Those smokey charges of civil war battles are probably not part of this particular reenactment in Galacia.[11] [12]

Inuyasha and the Warring States Period

The end of the Middle Ages for Japan is called the Warring States period. It begins with the Onin War but this war between two individuals will expand to become a nation-wide war that will last 10 years. Many wars will follow until 1568 when three powerful figures will rise up and bring stability to Japan. In the modern day when the people of Kyoto talk about the time "after the war" they aren't talking about World War 2. They are talking about the time after the Warring States. [13] [14] [15]
My Take by Alex Shrugged
I mentioned the cartoon character, Inuyasha, because the premise of the Japanese anime TV show of the same name is that a modern Japanese girl falls down a magic well and goes back in time to the Warring States period in Japan where she meets a magical creature named Inuyasha. The show makes such a point of the Warring States, that I remembered it, but beyond that, the cartoon itself bears little resemblance to any reality, past or present. Several video games are set during this period, including Shogun Total War and Age of Empires III: The Asian Dynasties. Occasionally the film Seven Samurai (1954) will show up on the TCM channel. It is actually a good movie.[16] [17]
