Way before 1776, history was happening which related to the future establishment of America (aka, Plato's Ideal, the 'New Atlantis', etc) - events of great consequence such as this:

A Few Brief Astro-Notes concerning July 28, 1588 (NS) 'noon' off the coast of England
Often what 'pops out' in a horoscope when looking at it for the first time are conjunctions of planets, how close are their positions by sign and degree, houses occupied (especially if a specific time is known for calculating the chart), and any other pertinent information. On the day Britain bested the Spanish Armada, the Sun @5Leo was separating from oceanic Neptune (1Leo21), traveler Mercury @22Leo22 was almost partile conjunct boundary breaker Jupiter (22Leo56), and warrior Mars @14Cancer trined rebellious Uranus in mid-Pisces and squared powerful Pluto at critical degree (12Aries).
Significantly, a Jupiter-Saturn square applied (5A32; from Leo to Saturn in late Taurus) and Saturn and Neptune were sextile (2A53) denoting a time of idealism vs pragmatism. It seems the naval battle for both countries took large amounts of planning but for someone, the follow through was lacking and certain rules may have been bypassed. Obviously, this sextile's opportunity for violating the space of others was operative and may also be one area where Mercury-Jupiter's planning came in.
Curiously enough, the Lunar Eclipse of February 10, 2017 @22Leo falls directly upon 1588's Mercury-Jupiter conjunction and may uncover, as all 'wild card' eclipses are wont to do, previously unknown plans for expansion and/or conquest especially in relation to Britain, America, Spain, or another realm currently under a monarchic system. (That America groans under such a system is hardly debatable these days, though you're welcome to disagree).
Unfortunately for my own understanding of this long ago event (if not for yours), there are discrepancies in the listing of Solar Eclipses in Brady's Predictive Astrology so that the famous 1588 naval conflict's Prenatal Eclipse Series' themes are unknown because its particular Saros Series ended years ago. As for the Fire-Air Sun Leo-Moon Libra combination of energies that day (which seem more applicable to the event than if an earlier Moon in Virgo is used), one of the Harveys' Images for Integration may be relevant to this important historic event and the era in which it occurred. See if you agree:
Sun Leo-Moon Libra: "A monarch discusses poetry with a visiting diplomat." (Sun Sign-Moon Sign). Of course, one of the monarchs involved in this event was Queen Elizabeth I, a pragmatic, reliable double-Earth Sun Virgo-Moon Taurus personality born during the time of a Saturn-Uranus conjunction in Cancer, a planetary duo perfect for one involved with sociopolitical enterprises and for serving the needs of the masses via far-reaching, lofty ideals. And as you know, old orders can lead to new orders under the combined energies of Saturn and Uranus (past vs future).
Now another chart factor stands out for it conjoins the Aries Point of World Manifestation (00Aries00:00) and that's the July 28, 1588 position of the Uranus-Pluto midpoint @29Pis21, the revolutionary pairing of planets so often active during events whenever freedom, power, war, and explosions are involved. The Armada's defeat and the motivations behind the conflict relate to the establishment of the British Empire, eventually to the founding of the American Empire, and to the obsessive expansion of both. I mention Uranus-Pluto because Queen Elizabeth I's natal Neptune, planet of The Seas, was transited during the battle by that midpoint which gives an enlightening picture of potentials we may read as: transit Uranus-Pluto = natal Neptune: knowledge of human nature; delving deeply into supernatural realms (she did!); a peculiar nervous state when excited; the occult. (Ebertin, Tyl, Munkasey). Did Astrology guide the Queen's choices concerning this event? Surely she consulted her favored court astrologer John Dee! (His natal chart is linked, below).
Yet on another level, we may wish to read the midpoint picture more simply as 'war and powerful revolutionary events' (Uranus-Pluto) on the high seas (Neptune). Works for me.
Ultimately, Britain's defeat of the 'invincible' Spanish Armada inspired a wave of nationalism and bolstered increased interest in the colonization of the North American continent and the settlement and subsequent founding of America. Which is why some people call July 28, 1588 The Most Important Date in US History.
