STATES AND TERRITORIES OF THE UNITED STATES (DELAWARE).

In this post we will looking at Delaware and its territories, Its present and past governors and House of representative’s members.

INTRODUCTION.

Delaware occupies the northeastern portion of the Delmarva Peninsula and some islands and territory within the Delaware River. It is the second-smallest and sixth-least populous state, but also the sixth-most densely populated. Delaware’s largest city is Wilmington, while the state capital is Dover, the second-largest city in the state. The state is divided into three counties, having the lowest number of any state (unless one counts Louisiana and Alaska, which do not have counties, but parishes and boroughs respectively); from north to south, they are New Castle County, Kent County, and Sussex County. While the southern two counties have historically been predominantly agricultural, New Castle is more urbanized, being part of the Delaware Valley Metropolitan Statistical Area centered on Philadelphia. Delaware’s geography, culture, and history combine elements of the Mid-Atlantic and Northeastern regions of the country. Before its coastline was explored by Europeans in the 16th century, Delaware was inhabited by several groups of Native Americans, including the Lenape in the north and Nanticoke in the south. It was initially colonized by Dutch traders at Zwaanendael, near the present town of Lewes, in 1631. Delaware was one of the Thirteen Colonies that took part in the American Revolution. On December 7, 1787, Delaware became the first state to ratify the Constitution of the United States, and has since been known as The First State. Since the turn of the 20th century, Delaware is also a de facto onshore corporate haven, in which by virtue of its corporate laws, the state is the domicile of over half of all NYSE-listed business and over three-fifths of the Fortune 500. The Dutch were the first Europeans to settle in present-day Delaware in the middle region by establishing a trading post at Zwaanendael, near the site of Lewes in 1631. Within a year all the settlers were killed in a dispute with area Native American tribes. In 1638 New Sweden, a Swedish trading post and colony, was established at Fort. Christina (now in Wilmington) by Peter Minuit at the head of a group of Swedes, Finns and Dutch. The colony of New Sweden lasted 17 years. In 1651 the Dutch, reinvigorated by the leadership of Peter Stuyvesant, established a fort at present-day New Castle, and in 1655 they conquered the New Sweden colony, annexing it into the Dutch New Netherland. Only nine years later, in 1664, the Dutch were conquered by a fleet of English ships by Sir Robert Carr under the direction of James, the Duke of York. Fighting off a prior claim by Cecil Calvert, 2nd Baron Baltimore, Proprietor of Maryland, the Duke passed his somewhat dubious ownership on to William Penn in 1682. Penn strongly desired access to the sea for his Pennsylvania province and leased what then came to be known as the “Lower Counties on the Delaware.

DELAWARE TERRITORIES.

Delaware is a state in the Mid-Atlantic region of the United States, bordering Maryland to its south and west; Pennsylvania to its north; and New Jersey and the Atlantic Ocean to its east. The state takes its name from the nearby Delaware River, in turn named after Thomas West, 3rd Baron De La Warr, an English nobleman and Virginia’s first colonial governor. Delaware occupies the northeastern portion of the Delmarva Peninsula and some islands and territory within the Delaware River. It is the second-smallest and sixth-least populous state, but also the sixth-most densely populated. Delaware’s largest city is Wilmington, while the state capital is Dover, the second-largest city in the state. The state is divided into three counties, having the lowest number of any state (unless one counts Louisiana and Alaska, which do not have counties, but parishes and boroughs respectively); from north to south, they are New Castle County, Kent County, and Sussex County. While the southern two counties have historically been predominantly agricultural, New Castle is more urbanized, being part of the Delaware Valley Metropolitan Statistical Area centered on Philadelphia. Delaware’s geography, culture, and history combine elements of the Mid-Atlantic and Northeastern regions of the country. Before its coastline was explored by Europeans in the 16th century, Delaware was inhabited by several groups of Native Americans, including the Lenape in the north and Nanticoke in the south.

LIST OF GOVERNORS AND HOUSE OF REPRESENTATIVE’S MEMBERS.

Before 1776, Delaware was a colony of the Kingdom of Great Britain, administered by colonial governors in Pennsylvania as the “Lower Counties on Delaware”. In 1776, soon after Delaware and the other Thirteen Colonies declared independence from Britain, the state adopted its first state constitution. It created the office of President of Delaware, a chief executive to be chosen by the legislature to serve a term of three years. The office of President was renamed Governor by the constitution of 1792, which set the commencement date of the term to the third Tuesday in the January following an election, and limited governors to serving only three out of any six years. The term was lengthened to four years by the 1831 constitution, but governors were limited to a single term. The current constitution of 1897 allows governors to serve two terms. The 1776 constitution stated that if the presidency were vacant, the speaker of the legislative council would be a vice-president. The 1792 constitution has the speaker of the senate exercising the office when it is vacant, and the 1897 constitution created the office of lieutenant governor, upon whom the office devolves in case of vacancy. The offices of governor and lieutenant governor are elected at the same time but not on the same ticket.

MEMBERS OF REPRESENTATIVES TO THE U.S. HOUSE FROM DELAWARE.

This is a complete list of members of the United States House of Representatives from Delaware. Elections are by a popular vote originally elected on the first Tuesday of October, but after 1831 on the first Tuesday after November 1. Terms began on the subsequent March 4 until 1935, from when they began on January 3. Delaware has had only one U.S. Representative, except for 10 years between 1813 and 1823, when there was a second U.S. Representative. This person was elected statewide, at-large, on the same ballot as the first U.S. Representative. The two candidates with the highest number of votes were elected.
