CATHERINE THE GREAT

The reign of Catherine II (Catherine the Great) is known to history as the “Age of Enlightened Absolutism,” in Russia. A whole generation of people grew up enjoying freedom of speech, political stability, and great victories.

BACKGROUND
After the death of Elizabeth, her nephew, Peter III, from Northern Germany ruled disastrously. His wife, Sophie Friederike Auguste, was a pretty German princess who had been invited to Russia while still very young. She converted to Orthodoxy, learned the Russian language, and took the name Catherine. In 1762, she launched a coup against her husband and became the Empress of Russia, known as Catherine the Great.

ENLIGHTENED MONARCH
Catherine continued Peter the Great’s line of modernization, and she strongly supported education and culture. She prepared drafted laws based on the views of the Enlightenment, but the greater part of her ambitious plans, including the abolition of serfdom, led nowhere.

PATRON OF NOBILITY
The great Administration Reform of 1775 increased the administrative power of the nobility. Courts and police institutions were established. The reform significantly increased the effectiveness of local government in Russia.

FOREIGN POLICY
In the beginning, Catherine’s foreign policy was in the hands of Nikita Panin. The commanders Alexander Suvorov, Fyodor Ushakov, and Grigory Potemkin, greatly expanded Russia’s territory in the south and west. In 1784, Crimea was taken from the Ottomans, and the three partitions, formed in 1772, 1793 and 1795, respectively, completely wiped Poland off the map.

PUGACHEV'S REBELLION
Catherine supported the Enlightenment only to a certain extent. She denounced the French Revolution as a brutal act against monarchy.

Although Catherine tried to improve the situation of Russian peasants, these attempts were mostly futile and caused unrest. In 1773, the greatest armed revolt in Russia, constituting 100,000 Cossacks, led by Yemelyan Pugachev, who claimed that he was actually Peter III, was put down ruthlessly. Pugachev was publicly executed.

Improved math is a channel created to provide additional instruction on essential math concepts. I’m passionate about math and I know first-hand how important math concepts are in the real world.

Teachers, parents, guardians, homeschoolers, and students can use these videos to help reinforce math skills. These math videos are designed to help teach yourself math or provide self-study math tools to assist when additional instruction is needed. Teaching math and learning math has changed the way many students learn in this virtual environment and during the pandemic. Having on-demand math videos can provide math tutoring needed when children are not able to get help from their teachers after school hours or when trying to do math at home.

The library of math tutorials that I create can also be used as supplemental instructional material for homeschool math. Each full-length video comes with a subsequent knowledge check or math practice problems which serve as a virtual math topic worksheet to test your understanding of each skill. These videos can be paused to work out the problems on your own, then unpaused to check your answers. All of these videos can be found under the Knowledge Check playlist.

I also have a library of shorter videos (less than 1 minute in length - shorts) that are quick math tips and tricks on basic math topics. Some of these short math help videos include problems that you can work on yourself and submit your answers in the comments. They are all listed under my Math Tips and Tricks playlist.

Improved math is creating more videos every day to cover topics from 4th grade, 5th grade, 6th grade, and 7th-grade math. The videos focus on fractions, basic math operations, geometry, and ratios but more topics are being added all the time. If there is a specific topic you would like to see covered, drop me a comment in one of my videos and let me know!

Free math help videos will be posted every Thursday and Friday. For additional math resources, check out my math help website at improvedmath.com where I post math worksheets and answers along with additional context on math basics.

Thanks for watching my channel.
