Revelation 3:14 is where you will find the letter. At that time, the city of Laodicea was a wealthy trading and medical city. Ideal for the vision of riches and the problems of riches. The name Laodicea means “people's rights,” and has there ever been a time when people's rights have been more of an issue? It is sometimes translated as “the people judged". When the Age begins, the industrial revolution is well underway. Worldwide trade is making many people rich, and that is reflected in the church and the congregations also becoming wealthy. This age of widespread wealth started in the 1800s. We see that 1844 is a significant date, but it is more accurate to say the Age of Laodicea starts in the 1840s.
Laodicea is the last letter and will run through to the second advent of Christ. When did it start? There is a famous picture of Jesus standing at a door and knocking. The door has a handle only on the inside. This was painted in 1851. It is called “The Light of the World” by Holman Hunt. Behold, I stand at the door and knock is written under it. Rev 3.20 Another clue to this age starting in the mid-1800s is Daniel 8:14. Daniels talks about 2300 days, which, when converted to a day, is a year. 2300 years from when the temple started to be rebuilt. That takes us up to 1844. Some movements claimed that Jesus would return then. It was felt that if the arrival of the messiah had a seventy-week prediction and two parts proved to be accurate, then the 2300 days would be accurate as well. The movement in the United States was called Millerism, but it was also called Adventism. It caused a great deal of embarrassment when it proved to be wrong. Why was their interpretation wrong? Let us look a little closer at Millerism and what was widely believed at the time. The physicist Isaac Newton had also noticed these numbers, and in his writing he had calculated a date for the return of Christ. For some reason known only to him, he took it from the time of Christ and as a result, he came up with some time in the 2300s. So William Miller was not a crackpot.

Millerism

William Miller was a lay preacher and student of the word. He saw that the seventy-week prophecy was exactly right, and there was another period in Daniel 8. He worked out a timeline based on some dates. So, the only start date he could come up with was the one that started seventy weeks. When he calculated it out, the date was 1844. He started to preach this and started a magazine called Signs of the Times. This spread around the world. However, it proved to be wrong. There were many reasons given for why it did not occur. The scripture read, “and the giving over of the sanctuary and host to be trampled underfoot?” And he said to me, “For 2,300 evenings and mornings. Then the sanctuary shall be restored to its rightful state.” They took restored to be an instant event and a moment in time, but it was the start of a process. The end of the age in Revelations and Matthew is a series of events. So, not the second coming, but the beginning of the events that would result in the second coming. Not the second coming, but the start of the age of Laodicea and the release of the white rider. 
Other events took place in 1844. The history of the Bahá'í faith goes back to 1844, when a young Iranian man who called himself the Báb said that God would soon send a messenger who was to be the latest prophet. Joseph Smith, the founder of the Mormon faith, was murdered. But more importantly, Bingham Young, the real driving force behind the religion, took over. Furthermore, the YMCA started. The rise of false religions is covered more in the White Rider, which we will see later. Many more things started that would change the world in the 1840s.

Charles Darwin and evolution

Even though The Origin of the Species was published in 1857, it was written before that date. On January 11, 1844, Darwin mentioned his theorising to the botanist Joseph Hooker, writing with melodramatic humour, “It is like confessing a murder”. Hooker replied, “There may, in my opinion, have been a series of productions on different spots and also a gradual change of species. I shall be delighted to hear how you think that this change may have taken place, as no presently conceived opinions satisfy me on the subject.”
By July, Darwin had expanded his “sketch” into a 230-page “essay,”, to be expanded with his research results if he died prematurely. In November 1844, the anonymously published sensational bestseller “The Natural History of Creation" was published.

Karl Marx and Socialism/Communism.

Karl Marx was a writer for various radical magazines and an activist. In 1844, Marx met with another activist named Friedrich Engels. Engels had just spent two years in England and had written 'The Condition of the Working Class in England'. This greatly influenced Marx. They worked together, and then Marx worked alone. By the end of the year, he had written in great detail all the major components of what we today call the Communist Manifesto. People's rights and the meaning of the name Laodicea.

Samuel Morse

The first electronic transmission sent in Morse code was sent on May 24th, 1844. The beginning of electronic communication and the age of computing. What is needed for the mark of the beast? The first message sent by Samuel Morse was “What has God wrought”. Truly a profound statement. This little device changed the world more than any other invention.

Karl Benz
Even though Karl Benz's inventions were at the end of the century, Karl was born in 1844. His patents include the battery spark ignition system, the carburettor, clutch, gear shift, radiator, and the speed regulation system. With the support of his wife, a remarkable woman, they drove the auto industry into existence.

Pope Pius XII

Pope Pius XII became the new Pope, taking over from Gregory XV1. This did not happen in 1844, but in 1846. Understanding what happened here is important to understanding the age of Laodicea and the next chapter, The White Rider. I will remind you that Laodicea means “people's rights”. Pope Pius was the first of the so-called liberal popes. Pope Gregory, being an orthodox pope, believed in the divine hand on the pope, God's infallibility, and his ultimate authority. Under Pope Pius, there were new rights given to various groups and committees. Gregory's authoritarian power was based on the model given by God and his authority. Now, groups of men were given the right to make a judgement on what God meant. This is where the role of the White Rider takes over, until finally, today, we have a non-Christian Pope (Jesuit).
The four most profound events that affect our modern times all came about in the same year, 1844. The year that the Age of Laodicea began. Within two years, the last of the four had occurred.
It was the end of the years that Daniel covered and the start of Revelations. Except for Daniel 7 and 9, Revelation now takes up the end of the age.
