Zinder IV is an urban commune in Niger. It is a commune of the city of Zinder.

Zinder (which is locally called Damagaram) is the second largest city in Niger, with a population of 170,574 (2001 census) by 2005 was estimated to be over 200,000. It is situated 861 km (535 mi) east of the capital Niamey and 240 km (150 mi) north of the Nigerian city of Kano.

Zinder rose from a small Hausa village to an important center of the Trans-Saharan trade with the founding of the Sultanate of Damagaram in 1736 by Kanouri aristocrats. The large fortress of the southeast central city (Birini) was built shortly thereafter, and became a major hub for trade south through Kano and east to Bornu. The Tuareg encampments and trade houses of the Hausa town (Zengou) expanded with this trade. The French conquered the city in 1899, and placed the capital of the new Niger Military Territory there in 1911. In 1926, following fears of Hausa revolts and improving relations with the Djerma of the west, the capital was transferred back to the village of Niamey.

Today, Zinder comprises three main areas. Birni, the old town, is home to Zinder Great Mosque and the Zinder Sultan's Palace, as well as a museum. Zengou or Zango, the old Hausa settlement, is known for its vernacular architecture. Sabon Gari (the new town), between Birni and Zengou, is the commercial centre, known for its large market. The city now sprawls to the north and west, extending to the Karkada section, in the north. Other neighborhoods include Garin Mallam and Gawon Kollia.

Robin Wayne Zander (born 23 January 1953) is the lead singer and rhythm guitarist for the rock band Cheap Trick.

Zander was born in Beloit, Wisconsin, the fourth of five children; he has two older brothers, and older and younger sisters.

Zander reportedly was reading books by age three, and learned to play the guitar by age 12. He played with his first group, The Destinations, while in seventh grade. The next year he was with a group called Butterscotch Sundays, playing summer festivals, and after that formed a band called Robin and the Hoods. In high school, Zander sang for three years in the Madrigals, the most demanding of the three choral groups at his school, played basketball and football, and had a part-time job at a sandwich shop.

In 1972, Zander was offered the lead singer role in a new band called Cheap Trick by the group's drummer, Bun E. Carlos. At the time, Zander was under contract with a resort in Wisconsin Dells, where he sang and played cover songs, and Cheap Trick had a lead vocalist, Randy "Xeno" Hogan. Hogan left the band around the same time Zander's resort contract expired, and Zander joined Cheap Trick as lead singer. Guitarist Rick Nielsen introduces Zander at concerts as his "favorite lead singer in the whole wide world".
