1.- Liquidation of debt and forced sales.

2.- Reduction in the money supply because the bank debts were liquidated.

3.- A fall in asset price levels.

4.- An even greater fall in the total value of companies, precipitating bankruptcies.

5.- A fall in profits.

6.- A reduction in production, trade and employment.

7.- Pessimism and loss of confidence.

8.- Accumulation of money.

9.- A fall in nominal interest rates and a rise in interest rates adjusted for deflation.

She restored the use of icons after her husband's death

Explanation:

The Iconoclastic Controversy was a political-religious phenomenon that occurred in the Byzantine Empire, also known as the Eastern Roman Empire, between the eighth and ninth centuries. The term iconoclastia is composed of two radicals of the Greek language: "eikóne" (icon), which means image, and "klastein", which means break, break. Therefore, the iconoclast is the one who destroys images.  But what kind of image was destroyed in the period of the Byzantine Empire? Images representing the leading personalities of Christianity, beginning with Christ Himself, followed by the Virgin Mary, apostles, saints, martyrs, and angels.

The iconoclastic fury instituted had a brief break of three years (787 to 789), at the time when Empress Irene of Athens reigned. The veneration of images was effectively restored only in the Byzantine Empire with the rise of Empress Regent Teodora (wife of Theophilus and mother of Michael III, who was regent from 842 to 855, after her husband's death), in the year 843, with the so-called Triumph of Orthodoxy. Empress Theodora restored the use of icons after the death of her husband Theophilus and thus ended the Iconoclastic Controversy.
