Government debt is the total amount of money that a government owes to its creditors, including individuals, businesses, and other governments.

Government debt can be classified into different types based on various factors such as the source of the debt, the maturity of the debt, and the currency in which the debt is denominated.

Internal debt is owed to domestic creditors, while external debt is owed to foreign creditors. Internal debt is typically denominated in the domestic currency, while external debt is denominated in foreign currencies. Internal debt has a shorter maturity than external debt.

Government debt can be caused by a variety of factors, including budget deficits, economic downturns, wars and emergencies, and other factors that lead to an increase in government spending or a decrease in government revenue.

High levels of government debt can lead to a number of negative consequences, including higher interest rates, reduced economic growth, inflation, and a decrease in the value of the domestic currency.

Governments can reduce their debt by increasing taxes, cutting spending, selling assets, or a combination of these measures.
