===Need for insurance===
The basic requirements of communal interests gave rise to risk sharing since the dawn of civilization.{{sfn|Loan|1992}} <!-- From here to end supported by Lewin -->For example, people who lived their entire lives in a camp had the risk of fire, which would leave their band or family without shelter. After [[barter (economics)|barter]] came into existence, more complex risks emerged and new forms of risk manifested. Merchants embarking on trade journeys bore the risk of losing goods entrusted to them, their own possessions, or even their lives.  Intermediaries developed to warehouse and trade goods, which exposed them to [[financial risk]]. The primary providers in extended families or households ran the risk of premature death, disability or infirmity, which could leave their dependents to starve. [[Credit (finance)|Credit]] procurement was difficult if the creditor worried about repayment in the event of the borrower's death or infirmity. Alternatively, people sometimes lived too long from a financial perspective, exhausting their savings, if any, or becoming a burden on others in the extended family or society.{{sfn|Lewin|2007|pp=3–4}}
